“…Its surface reactivity is defined by particle morphology. 43 It possesses lattice oxygen vacancies, consisting of an electron pair (2e -) in a ZnO lattice structure, which is considered to be one kind of active site for methanol synthesis. Zn 2+ -2epairs move interstitially, leaving cation and anion lattice vacancies, which is beneficial to the adsorption and transformation of the reactant.…”

Since the start of last century, methanol synthesis has attracted great interests because of its importance in chemical industries and its potential as an environmentally friendly energy carrier. The catalyst for the methanol synthesis has been a key area of research in order to optimize the reaction process. In the literature, the nature of the active site and the effects of the promoter and support have been extensively investigated. In this updated review, the recent progresses in the catalyst innovation, optimization of the reaction conditions, reaction mechanism, and catalyst performance in methanol synthesis are comprehensively discussed. Key issues of catalyst improvement are highlighted, and areas of priority in R&D are identified in the conclusions.

Agradeço primeiramente à vida, por me dar a oportunidade de estar aqui hoje. Agradeço aos meus queridos pais, Luiz Carlos e Clarice por sempre me apoiarem e aconselharem em minhas decisões e nunca desistirem de mim. Por todo o carinho e atenção que tive durante minha vida, pela educação que foi me dada, pela pessoa que sou hoje. Agradeço também a toda minha família, meu irmão (Luiz Junior) e meu sobrinho (Samuel), que, apesar de minha ausência sempre estiveram ao meu lado. Agradeço ao meu namorado e amigo, Filipe, que me ouve, aconselha e ajuda em todas as áreas da minha vida, seja acadêmica, profissional ou pessoal. Agradeço também à Mãe do Filipe (Márcia) e aos irmãos (Ester e Mateus) por sempre me receberam com carinho em Poços de Caldas. Agradeço à Prof. Dra. Elisabete Assaf pela orientação e amizade e por me apoiar e acreditar em mim nos momentos difíceis. Agradeço aos meus amigos de faculdade que continuam me apoiando, especialmente: Milene e Adriano, que apesar de estarem distantes fisicamente no momento, sempre estão dispostos a conversar; Eduardo (Spin) que é um amigo que admiro muito (mesmo sem ele saber).
