depolymerization of lignin. Ni/La-ZrO2 catalyst (Yabe) shows very high catalytic activity even at temperatures as low as 473 K in the dry reforming of methane. A minimalistic solventless synthesis protocol (Chuah) gives easy access to layered αzirconium diammonium phosphate and to phase pure monoclinic/tetragonal zirconia in high yields. Shao developed a method for SrCo0.6Ti0.4O3−δ@CoOOH nanocomposites, which can significantly improve the catalytic activation and stability of pristine perovskite in catalytic applications. We thank all the authors and reviewers whose timely efforts made it possible to produce this fine collection of papers and the editorial team of ACS Sustainable Chemistry & Engineering for their great support. The papers presented in this VSI combine novel catalyst design and synthesis with advanced characterization and efficient reaction processes. The disseminated knowledge will advance the rational design of highperformance catalysts for addressing some of the grand challenges in the energy and chemical industries.
ue to impending depletion of fossil-based resources and increasing global demand for energy and chemicals, new catalysts are essential for efficient conversion of raw (both fossil and renewable) materials to valuable products and development of more sustainable chemical manufacturing processes. Such processes are characterized by selective acceleration of chemical transformations to specific products while reducing the energy needed, and, thus, use fewer resources and generate less waste. The societal value of catalysts extends well beyond product development, to the environment and quality of life via waste treatment and greenhouse gases reduction. The global sustainability requires an entirely new level of understanding and mastering of catalysts from design to fabrication to end-user performance. The “Tailoring Resource-Efficient Catalysts for Sustainable Energy and Chemical Processes” Virtual Special Issue’s (VSI) numerous articles highlight recent developments on photocatalysts, electrocatalysts and heterogeneous catalysts for the efficient production of sustainable energy and chemicals as well as CO2 reduction {http://axial.acs.org/2019/04/01/catalystssustainable-energy/}. Regarding photocatalysts, Chen’s Perspective focuses on the design and construction of bismuthbased solar-conversion systems for H 2 evolution, CO 2 reduction, and N2 fixation. Ag−Cr core−shell-structured cocatalyst on Ga2O3 (Teramura) and Ru(II)-complex/C3N4 hybrid photocatalysts (Maeda) have been developed for highly selective photocatalytic CO2 reduction. Yin reports TiO2/ Bi2MoO6 composites as stable and efficient photocatalysts for the partial oxidation of aromatic alkanes under ambient conditions. For electrocatalysts, Wang summarizes the anion and cation vacancies and heteroatoms doping of electrocatalysts in water splitting for sustainably producing hydrogen. The covalent immobilization of Mn-based molecular catalysts (Jiang) and a trimetallic (Co/Ni/Cu) hydroxyphosphate nanosheet array (Guo) are efficient and durable electrocatalysts. Many articles in the VSI are in the area of heterogeneous catalysts. Ru/La0.5Pr0.5O1.75 (Nagaoka) and Ru/Nb2O5·nH2O (Hara) catalysts show the outstanding activity in lowtemperature ammonia synthesis and reductive amination of biomass-derived carbonyl. Shishido develops supported Pd− Au alloy catalysts for reversible hydrogen storage-release process involving ammonium formate and bicarbonate. Jia synthesizes POM@Zr-MOFs for olefin epoxidation with either H2O2 or O2 as a green oxidant. Otomo reports the selective dehydration of biobased 1,2-propanediol to propanal on boron phosphate catalyst. Ni phyllosilicate with controlled morphology (Yuan) has been synthesized for the deep hydrogenation of polycyclic aromatic hydrocarbons. H-MOR (Ma), SAPO-34 (Wang), and hierarchical ZSM-5 (Han) zeolites have been prepared with tunable acidity and porous structure for dimethyl ether carbonylation, sustainable olefin production, and hydrocarbons cracking. Cu(OH)2+Fe2O3 bimetallic catalyst (Wu) shows the high performance for oxidative © 2019 American Chemical Society
