First-row transition metals have thus been brought to light in the search for efficient and high-performance homogenous molecule catalysts that can accelerate energy transformation and reduce overpotentials during the catalytic process. Their dinuclear complexes have opportunities to enhance the efficiency and stability of these molecular catalysts, primarily for the hydrogen evolution reaction (HER) and water oxidation reaction (WOR). Recently, our group improved the catalytic activity, efficiencies, and stability of dinuclear molecular catalysts, particularly toward HER. Although one dinuclear complex has been tested for WOR, it demonstrated activity as water oxidation precatalysts. First-row transition metals are a great option for sustainable catalysis because they are readily available, reasonably priced, and have multifaceted coordination chemistry. Examples of these metals are cobalt, copper, and manganese. The structure-catalytic performance relationships of this first-row transition metal-based dinuclear catalysts are noteworthily interpreted in this account, providing avenues for optimizing their performance and advancing the development of sustainable and effective energy conversion technologies.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":"25 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142806187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Formic acid is a simple carboxylic acid with a high hydrogen concentration and is generally stable, making it useful as a hydrogen transporter. Catalytic dehydrogenation is usually used to extract hydrogen from formic acid; this process releases hydrogen gas and yields carbon dioxide as a byproduct. Comparing this technology to conventional hydrogen generation methods, there are several benefits, such as the utilization of the formic acid handling infrastructure already in place and the possibility of a simpler integration into different energy systems. Notwithstanding, several obstacles persist, including enhancing the effectiveness of the dehydrogenation procedure and reducing the ecological consequences of the correlated carbon dioxide discharges. Catalysts, reaction conditions, and carbon collection and utilization methodologies are all being researched further. The development of Ru and Cu-based catalysts for the catalytic breakdown of HCOOH into CO2 and H2 is the main topic of this account. Herein, the focus is on the kinetic studies of HCOOH dehydrogenation, encompassing mechanistic investigations that consider intermediate studies and DFT calculations.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":"24 12","pages":""},"PeriodicalIF":7.0,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142766657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study discusses the pathway for deploying adsorption-based carbon capture technology in fundamental material science aspects, thermo-physical properties behavior at the molecular level, and industrial pilot scale demonstrations. When integrated with process simulation and economic evaluations, these techniques are instrumental in enhancing the efficiency and cost-effectiveness of the capturing processes. While advancements in adsorption-based carbon capture technologies have been notable, their deployment still encounters significant hurdles, including technical, economic, and environmental challenges.

Fossil fuel overuse damages the environment and raises sustainability concerns. As a resource-rich element, cobalt oxide hybrids have attracted considerable attention as low-priced and eco-friendly electrocatalysts. Alkaline solutions disperse Co3O4 easily despite its highly stable nature, which arises from the reverse spinel structures of Co. Metal oxides, nickel foam, polymeric frameworks, and carbon nanotubes have been successfully served to combine with the Co3O4 constructions for improving the electrocatalytic performance. To date, no comprehensive study has systematically investigated the relation between the cobalt oxide hybrid's physicochemical-electronic aspects and its catalytic features. This review mainly focuses on material design, fabrication, morphology, structural characteristics, and electroactivity, considering the critical factors towards practical applications. The economic impacts of the constructions and their expected contribution to large-scale utilizations are also demonstrated. Moreover, this research discusses the synergistic effects of crucial electrochemical parameters on sustainable energy production over the Co3O4-based hybrids.

In recent years, the catalytic insertion of a single nitrogen atom into carbocycles, leading to N-heterocycles, has become an important focus of modern synthetic approaches with applications in medicinal chemistry, materials science, and industry. Catalytic single-nitrogen-atom insertions have been increasing in prominence in modern organic synthesis due to their capability to construct high-value added nitrogen-containing heterocycles from simple feedstocks.

Since the early 2010s, PDT has advanced significantly, with the focus shifting toward the exploration of molecules capable of thermally activated delayed fluorescence (TADF) as viable alternatives to traditional metallic complexes and organometallic compounds for producing the necessary active species. TADF molecules exhibit higher energy conversion efficiency, long-lived triplet excitons, tunable photophysical properties, and a small singlet-triplet energy gap, facilitating efficient intersystem crossing and enhanced singlet oxygen generation. As metal-free luminophores, they offer benefits such as reduced health risks, high structural flexibility, and biocompatibility, which can significantly enhance PDT treatment efficacy. Notably, in 2019, a pivotal shift occurred, with researchers concentrating their efforts on identifying and investing in potential molecules specifically for Type II PDT applications. This review presents the innovative use of materials characterized by closely spaced S1 and T1 orbitals, crucial for the efficient generation of singlet oxygen in PDT. Exploring these materials opens new avenues for enhancing the efficacy and specificity of PDT, offering promising for future cancer treatments.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":"24 12","pages":""},"PeriodicalIF":7.0,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142726187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
