摘 要:In this paper,we discuss the previous advances,current challenges,and future opportunities for the research of catalytic reduction of water *** present five case studies on the development of palladium-based catalysts for nitrate,chlorate,and perchlorate reduction with hydrogen gas under ambient *** emphasize the realization of new functionalities through the screening and design of catalytic metal sites,including(i)platinum group metal(PGM)nanoparticles,(ii)the secondary metals for improving the reaction rate and product selectivity of nitrate reduction,(iii)oxygen-atom-transfer metal oxides for chlorate and perchlorate reduction,and(iv)ligand-enhanced coordination complexes for substantial activity *** also highlight the facile catalyst preparation approach that brought significant convenience to catalyst *** on our own studies,we then discuss directions of the catalyst research effort that are not immediately necessary or desirable,including(1)systematic study on the downstream aspects of under-developed catalysts,(2)random integration with hot concepts without a clear rationale,and(3)excessive and decorative *** further address some general concerns regarding using H2 and PGMs in the catalytic ***,we recommend future catalyst development in both“fundamentaland“applied*** purpose of this perspective is to remove major misconceptions about reductive catalysis research and bring back significant innovations for both scientific advancements and engineering applications to benefit environmental protection.
