Significant transformations - including extensive electrification of the sector - are necessary to achieve the climate change goals. To understand the new energy vehicle (NEV) policy research, we explore the status, knowledge base, and research frontiers of NEV policy research by studying 355 papers collected from the Web of Science Core Collection database. We map NEV policy research trends and knowledge structure development using knowledge domain technology and bibliometric techniques. The knowledge base analysis shows that (1) NEV policy formation and evaluation, (2) policy incentives and consumer adoption, and (3) consumer preferences towards NEV adoption are all essential knowledge foundations in NEV policy research and development. The efficiency of NEV policy, cost-effectiveness of alternative fuel vehicles (AFVs), consumer preferences for NEV adoption, hydrogen energy and fuel cell vehicles, climate policy and CO2 emissions are five main lines of research in NEV policy studies. With the highest publications from Tsinghua University, China is the most active country in NEV policy research. Energy Policy, Sustainability, and Journal of Cleaner Production are the core journals, and energy and fuels and environmental sciences are the core disciplines of NEV policy research. The findings of this analysis help policymakers and researchers to navigate the literature on NEV, provide a clear map of existing works, identify the gaps and recommend promising avenues for future studies.","PeriodicalId":14807,"journal":{"name":"Johnson Matthey Technology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67352027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a drive to augment traditional transition metal catalysts with green alternatives such as biocatalysts. Transaminase (TA) biocatalysts can be used in combination with \"smart\" sacrificial amine donors to synthesise a variety of aliphatic and aromatic amines from the corresponding aldehydes and ketones. Despite their enormous potential, the unfavourable reaction equilibrium often limits the widespread application of TAs for industrial synthesis. Recently we disclosed a new biomimetic amine donor N-phenyl putrescine (NPP), which was inspired by the biosynthesis of the dipyrroloquinoline alkaloids. NPP was demonstrated to have good activity with a library of commercial and wild-type TAs (total 25 TAs). This work focused on exploring the use of NPP with the Johnson Matthey TA kit (17 biocatalysts; 8 S-selective and 9 R-selective) and three different amine acceptors (vanillin, benzaldehyde and acetophenone). NPP worked well with all 17 TAs and gave the corresponding amine products vanillylamine, benzylamine and methylbenzylamine in up to 85% HPLC yield. From the screen, STA-14 was identified as a good biocatalyst for further analysis and used in a comparative screen of NPP versus the commonly used donor iPrNH2. It was found that NPP was the best amine donor and used to prepare S-methylbenzylamine in >99.5% e.e. This work, combined with our previous study, highlights the potential of NPP in the biocatalytic synthesis of amines.","PeriodicalId":14807,"journal":{"name":"Johnson Matthey Technology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67352295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Green ammonia utilisation methods are discussed with direct use cases such as ammonia combustion and direct ammonia fuel cells examined. Green ammonia’s potential as a carbon-free hydrogen carrier is also discussed in regards to ammonia cracking for effective hydrogen recovery.

The high activity of the catalyst causes the alkenes to form linear oligomers below room temperature. INS has shown that the reaction proceeds through a hydrogen-bonded intermediate. Studies using propane as an inert analogue for propene have found that the adsorbed C3 molecules spend the majority of their time undergoing short jumps within the pore channels of the zeolite. Hydrothermal de-alumination plays an important role in determining the activity of zeolite catalysts. De-alumination was found to delay the onset of catalytic activity for oligomerization to higher temperatures and increase the mobility of hydrocarbons within the zeolite, both due to reduced acid-hydrocarbon interactions.","PeriodicalId":14807,"journal":{"name":"Johnson Matthey Technology Review","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135954176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, some manufacturing methods of hydrogen consume large amounts of energy and produce carbon dioxide as a by-product. The production of hydrogen by bacteria is an attractive alternative, because it is not energy intensive and - under the right conditions - does not release greenhouse gases. In this review, we introduce the five known ways by which bacteria can evolve hydrogen. We then describe methods to encapsulate living bacteria in synthetic layers, called coatings, for applications in bioreactors. We review the few examples in which biocoatings have been used to produce hydrogen via the photo-fermentation method. Although not used in biocoatings so far, the dark fermentation method of hydrogen production avoids the need for illumination while offering a high yield with low oxygen evolution. We identify the potential for using genetically-modified bacteria in future research on biocoatings.","PeriodicalId":14807,"journal":{"name":"Johnson Matthey Technology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67352055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To enable scale-up of the technology to the terawatt level, further improvements in the iridium utilisation are needed, without incurring additional overpotential losses or reducing the device lifetime. The research community has only recently started to attempt systematic benchmarking of catalyst stability. Short term electrochemical methods alone are insufficient to predict catalyst degradation; they can both underestimate and overestimate catalyst durability. Complementary techniques, such as inductively coupled plasma - mass spectrometry, are required to provide more reliable assessment of the amount of catalyst lost through dissolution. Herein, we critically review the state of the art in probing degradation of iridium-based oxide catalysts. We also highlight considerations and best practices for the investigation of activity and stability of oxygen evolution catalysts via short term testing.","PeriodicalId":14807,"journal":{"name":"Johnson Matthey Technology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67352308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
