Promoters can also be used as structural, textural, electronic modifier, stabilizers, and catalyst-poison-resistant, which can improve the catalytic performance.

POM in fixed-bed reactors requires an oxygen separation plant with high operation cost and safety risks. On the contrary, membrane reactors can provide an improved process by integrating both oxygen separation and catalytic reaction processes. With many advantages including high purity and efficient oxygen separation from the air at the catalytic reaction conditions, mixed ionic-electronic conducting membranes (MIEC) caught great attention in the scientific research field over the past two decades. In this review, POM using different catalysts in fixed-bed reactors was firstly summarized with emphasizing on perovskite-based catalysts, and then the material screening of MIEC membrane reactors was introduced and linked to the selection of conventional and perovskite catalysts. The catalytic activity, reaction mechanisms, and emerging challenges have been analyzed. Furthermore, future research directions have been outlined by highlighting the effect of electronic properties, continuous reduction-oxidation in the presence of oxygen flux, and chemical reaction mechanism on membrane/catalyst.","PeriodicalId":9647,"journal":{"name":"Catalysis Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76496310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In both academic and industrial sectors, the development of efficient nanosized catalysts has received considerable attention because it can improve the efficiency of the catalytic process and the selectivity of products, which can minimize the overall production cost and the amount of chemical wastes generated by improving the atomic efficiency. However, bulk-scale synthesis and utilization of nanocatalysts are hindered by the high synthetic cost, tedious synthesis procedure, and difficulty in the separation and recovery of the catalysts after the reactions. In this context, superparamagnetic nanoparticles have attracted much attention as a catalyst and as a support owing to their robust structure, low cost, environmental benignity, and easy separation under an external magnetic response. In this review, we focused on organic catalysis and photocatalysis using magnetically retrievable core–shell nanocatalysts with various functionalities. This review presents a comprehensive overview of the synthesis of magnetic core–shell nanocatalysts with suitable functionalities for catalysis, recent developments in organic and photocatalytic reactions using core–shell catalysts, and challenges to be addressed as part of future research activities. The first part summarizes the various synthetic methods of magnetic nanocores, and the second part overviews the detailed functionalization methods for the growth of shells on the surface of the magnetic nanocores, along with the merits and challenges to-date. In the last section, the efficiency, recoverability, and reusability of magnetic core–shell nanocatalysts are reviewed for a variety of organic and photocatalytic reactions.","PeriodicalId":9647,"journal":{"name":"Catalysis Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85032245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Generally, the main synthetic method of s-tetrazine relied on the condensation of two nitriles to give the corresponding symmetric/asymmetric tetrazines with moderate to excellent yields. However, the practical synthesis route and commercial/synthetic availability of the feedstock nitriles are still elusive. It is therefore probably worth summarizing the existing methods and typical biological applications that have been demonstrated in recent years. In brief, this overview will be split into three parts. First, we will summarize the typical approaches toward the synthesis of s-tetrazines till now. Then, we will provide the representative bio-orthogonal reactions by the combination of s-tetrazines with unsaturated compounds under physiological conditions. Eventually, we will propose a direction for the practical and efficient synthesis of s-tetrazine.","PeriodicalId":9647,"journal":{"name":"Catalysis Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90981034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The two-bed catalytic system in one or two reactors involves glycerol dehydration to acrolein and subsequent oxidation of acrolein to acrylic acid. Zeolites, metal oxides, heteropoly acids, and phosphates are effective in the dehydration of glycerol to acrolein. Mo–V–O catalysts appear active in the acrolein oxidation to acrylic acid. The glycerol can be completely converted to acrolein with 98% selectivity. In such a two-step process, the step of catalytic dehydration is thought to be critical. A few recent studies reveal that the conversion of glycerol to acrylic acid in two reactors can be also achieved via allyl alcohol as intermediate. For the one-bed catalytic glycerol oxydehydration to acrylic acid, a single catalyst must possess both active acid sites and active redox sites. Mo–V–O, W–V–O, Mo–V–W–O, W–V–Nb–O oxide catalysts, and heteropoly acid catalysts are particularly promising. Currently, a 60% yield of acrylic acid can be achieved over H0.1Cs2.5(VO)0.2(PMo12O40)0.25(PW12O40)0.75 at 340°C. However, all the catalysts rapidly deactivate due to coking. Coking usually occurs during the glycerol oxydehydration step. Optimizing reaction conditions such as increasing water and oxygen feeding, lowering reaction temperature, tuning the catalysts by finely doping, adjusting the surface acidity and enlarging pores of the solid catalysts can inhibit coking to some extent by slowing the deactivation of catalyst. Yet coking over catalysts is a major obstacle when conducting glycerol oxydehydration on a large scale. We suggest that future work should place an emphasis on revealing the essence of coking, further designing coking-resisting catalysts, and developing an efficient reaction and separation system.","PeriodicalId":9647,"journal":{"name":"Catalysis Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85667122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, advanced oxidation technologies are gaining attention as an eﬀective method for wastewater treatment capable of degrading a diverse spectrum of organic contaminants. Photocatalysis is a promising advanced oxidation technology to alleviate water pollution problems. Titanium dioxide (TiO2) is the most popular photocatalyst due to its low cost, nontoxicity, high oxidizing abilities, and easy immobilization on various surfaces. The current review aims to highlight recent advancements in photocatalytic degradation of pesticides and major organic pollutants using TiO2-based photocatalysts. Indeed, most of the methods, which employed potent catalysts, showed and exhibited successful degradation of the pesticides under various conditions.
