For the adsorption of these gas molecules, NO is most easily adsorbed on h-BN monolayer with metal dopants, especially Pt doped system yields the lowest adsorption energy of NO. Since a NO molecule on Pt doped h-BN monolayer could not be directly decomposed into O_ads and N_ads due to the high reaction energy barrier (≈ 2.00 eV), the (NO)₂ dimmer can interact with Pt to form a five-membered ring or a four-membered ring through two different Langmuir–Hinshelwood (LH) mechanisms for NO reduction catalytic reaction, respectively. The LH1 reaction process needs to overcome relatively lower energy barriers, while the product of the LH2 mechanism has a more stable structure. For the catalytic process of CO oxidation, the remained O_ads can bind with CO and form CO₂, by overcoming a much lower energy barrier of only 0.14 eV.

Today the consumption of coal, natural gas, and oil is rising continuously worldwide. In contrast to fossil fuels, biofuels can be advantageous because of their eco-friendly behavior with the environment. Ethanol is the “green” substitute for gasoline, as it can be blended with gasoline or can be used for the production of lighter olefins (ethylene and propylene). Ethanol can be produced either by fermentation or by catalytic route from various sources such as sugar/starchy material, carbon dioxide, carbon monoxide, and dimethylether. The catalytic route has emerged as the better route compared to fermentation due to the requirement of a large number of crops which is generally not suitable for every country. The study of ethanol synthesis and the catalytic transformation of ethanol to lighter olefins such as ethylene and propylene is presented in this review. The effect of catalysts such as zirconia, alumina, and zeolites in the ethanol transformation to olefins has been discussed in detail.</p><h3>Graphic Abstract</h3>\u0000 <figure><div><div><div><picture><source><img></source></picture></div></div></div></figure>\u0000 </div>","PeriodicalId":509,"journal":{"name":"Catalysis Surveys from Asia","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2021-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"5382423","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}

Results show that the introduction of Cr, Fe, Ce and W substantially affects the physicochemical properties and catalytic performance of MoVTeNbO-based catalysts. Un-doped catalyst consists of M2 phase and TeO₂, while Cr, Fe, Ce and W-doped catalysts are mainly composed of M2 and MoO₃. It is indicated that doping of Cr, Fe, Ce and W can restrain the formation of TeO₂, but favour the formation of MoO₃. Un-doped, Cr and W-doped catalysts display irregular-shaped particles morphology, while Fe and Ce-doped catalysts display nanosheets morphology. In addition, the valence of superficial elements of catalysts changed greatly with the doping elements. For catalytic performance, in addition to Cr, the propylene conversion of the catalyst decreases obviously with doping of other elements, probably due to the drastically reduced specific surface area with doping of Fe, Ce and W. The existence of Cr and Ce can increase the selectivity to AA at all test temperatures (360–440 ℃), while Fe and W-doped catalysts only show higher selectivity than the un-doped one at high temperature of 420 and 440 ℃. It is illustrated that the catalysts with redox ability at relatively low temperature is more favorable for the selectivity to AA.
