Editorial: Small‐Structure Innovation of Catalysis Powers a Sustainable Future

To tackle the grand twin challenges of sustainable energy supply and climate change, Small Structures advanced catalysts can play a central role in not only promoting conversion such as green hydrogen production storage, but also mitigating green-house gas threats for value-added fuel conversion. Catalysis, one most active diversified research fields, is pivotal to achieving zero-emission target coming decades. The significant advancements have been witnessed material design, experimental technology, fundamental knowledge. document state-of-the-art these advances, this Special Issue features 7 articles 8 reviews, covering broad spectrum catalysis renewable storage: electrocatalysis, photocatalysis, photoelectrocatalysis, thermal catalysis. Focusing on water splitting reactions production, there are three review about design new including 2D metal-organic frameworks (MOFs) (Q Zhang et al., DOI: 10.1002/sstr.202200109) Ni-based MOFs (D H Taffa 10.1002/sstr.202200263), advances situ characterization platforms (J-F Li 10.1002/sstr.202200201). Four introduce photocatalytic processes based mesoporous semiconductors (R Marschall 10.1002/sstr.202200184) carbon nitride (L Wang 10.1002/sstr.202200264), photoelectrochemical oxidation using doped titania nanotubes (K Maeda 10.1002/sstr.202200229), porous electrocatalytic (Y Yamauchi 10.1002/sstr.202200235). B-Y Xia al. present their perspectives at larger scale, discussing strategies proton-exchange-membrane-based electrolyzers (DOI: 10.1002/sstr.202200130). mitigate dioxide impact our environment, Jang co-workers single-atom catalyst CO2 reduction 10.1002/sstr.202200236), R Xu article covalent organic framework CO2-to-CO 10.1002/sstr.202200233). J Scott's team focuses valuable light olefins 10.1002/sstr.202200285). Relating concept catalytic process products, G Wu electrochemical nitrate ammonia 10.1002/sstr.202200202), whereas Liang provide critical overview 10.1002/sstr.202200266). In article, K Nakajima's demonstrate strategy de-hydration glucose hydroxymethylfurfural (HMF) 10.1002/sstr.202200224). By synergistic catalysis, B-Q Li, Q Zhang, investigate high-performing an storage system lithium-sulfur batteries 10.1002/sstr.202200205). guest editors do wish special issue shed reaction mechanism understanding rational fast-growing field. We believe that sustained effort Structure innovation would make big change.
