Abstract Conventional suspension photocatalysts face stability and efficiency challenges in harsh, unconditioned environments characterized by high alkalinity, salinity, organic species seawater wastewater. Moreover, suspension‐based photothermal‐assisted catalysis presents further challenges, particularly concerning formation of heterojunctions between photothermal materials that disrupt charge‐transfer pathways are exacerbated heating‐induced carrier recombination. Here, a photocatalytic system is proposed which three key photoprocesses: photothermal, photogeneration‐charge separation, photoredox spatially decoupled yet coordinated, aimed at addressing prevalent adsorption‐mediated catalyst deactivation harsh environments. Essentially, the polymeric tandem catalytic (PTPC) film consists TiO 2 /Au CuS layers, separated encapsulated serve as spacer inhibitors to conflicting photochemical‐photothermal corrosion‐resistant redox medium. The PTPC exhibits enhanced light absorption, mass transfer, effect, surpassing traditional catalysts enabling interfacial reactions on passive surface. represents new paradigm photocatalysis, unimpeded photoredox‐photothermal for application hostile plastic waste Such can be used develop localized, onsite solutions H production minimize logistical environmental challenges.

Nature Communications, Год журнала: 2021, Номер 12(1)

Опубликована: Фев. 26, 2021

Abstract The design of efficient chiral catalysts is crucial importance since it allows generating enantiomerically pure compounds. Tremendous efforts have been made over the past decades regarding development materials with enantioselective properties for various potential applications ranging from sensing to catalysis and separation. Recently, features generated in mesoporous metals. Although these monometallic matrices show interesting enantioselectivity, they suffer rather low stability, constituting an important roadblock applications. Here, a straightforward strategy circumvent this limitation by using nanostructured platinum-iridium alloys presented. These can be successfully encoded information co-electrodeposition Pt Ir salts simultaneous presence compound lyotropic liquid crystal as asymmetric template mesoporogen, respectively. enable remarkable discrimination between compounds greatly improved enantioselectivity when used electrosynthesis (>95 %ee), combined high electrochemical stability.
