Fluid Field Modulation in Mass Transfer for Efficient Photocatalysis

Advanced Science, Journal Year: 2022, Volume and Issue: 9(28)

Published: Aug. 11, 2022

Abstract Mass transfer is an essential factor determining photocatalytic performance, which can be modulated by fluid field via manipulating the kinetic characteristics of photocatalysts and intermediates. Past decades have witnessed efforts achievements made in mass based on photocatalyst structure composition design, thus, a critical survey that scrutinizes recent progress this topic urgently necessitated. This review examines basic principles how behavior impacts activity accompanying with discussion theoretical simulation calculation including flow speed pattern. Meanwhile, newly emerged viable micro/nanomotors self‐thermophoresis, self‐diffusiophoresis, bubble‐propulsion mechanisms as well magnet‐actuated artificial cilia for facilitating will covered. Furthermore, their applications hydrogen evolution, carbon dioxide reduction, organic pollution degradation, bacteria disinfection so forth are scrutinized. Finally, brief summary future outlook presented, providing guideline to those working photocatalysis, transfer, other related fields.

Bifunctional BiPd Alloy Particles Anchored on Carbon Matrix for Reversible Zn–CO₂ Battery

ACS Applied Nano Materials, Journal Year: 2022, Volume and Issue: 5(9), P. 12387 - 12394

Published: Sept. 7, 2022

Exploring reversible Zn–CO2 batteries holds great promising potential for future CO2 fixation and energy supply. Herein, the bifunctional PdBi alloy anchoring on carbon substrate (BiPdC) is proposed simultaneously catalyzing dioxide reduction reaction (CO2RR) formic acid oxidation (FAO). The synergistic effect between Pd Bi overcomes sluggish kinetics of CO2RR FAO, causing HCOOH Faraday efficiency (FEHCOOH) 63.4% 6.2 mA cm–2 current density FAO. Benefiting from CO2–HCOOH interconversion, homemade battery exhibits optimal 52.6% FEHCOOH 1.1 V voltage gap within 45 h cycling.

Ionic Liquid‐Assisted Electrocatalytic NO Reduction to NH₃ by P‐Doped MoS₂

ChemCatChem, Journal Year: 2022, Volume and Issue: 15(3)

Published: Dec. 9, 2022

Abstract Ambient NH 3 electrosynthesis from NO reduction reaction (NORR) is attractive in replacing the industrial Haber‐Bosch route; however, competitive hydrogen evolution (HER) aqueous electrolyte typically induces a limited selectivity and activity toward production. Herein, hierarchical P‐doped MoS 2 nanospheres are developed as NORR electrocatalyst an ionic liquid (IL) for catalyzing of to with maximal Faradaic efficiency 69 % (−0.6 V vs RHE) peak yield rate 388.3 μg h −1 mg cat. (−0.7 RHE), both which comparable best‐reported results. Moreover, catalyst also shows stable over 30 6 cycles. Theoretical analyses further reveal that P dopants facilitate activation hydrogenation NO. Besides, employment hydrophobic IL slows down HER kinetics effectively.

Artificial photosynthesis bringing new vigor into plastic wastes

SmartMat, Journal Year: 2023, Volume and Issue: 4(4)

Published: March 29, 2023

Abstract The accumulation of plastic wastes in landfills and the environment threatens our public health, while leading to loss potential carbon resources. urgent necessary lies developing an energy‐saving environmentally benign approach upgrade into value‐added chemicals. Artificial photosynthesis holds ability realize upcycling by using endless solar energy under mild conditions, but remains initial stage for upgrading. In this review, we aim look critically at photocatalytic conversion from perspective resource reutilization. To begin with, present emerging routes highlight advantages artificial processing wastes. By parsing process, demonstrate currently available plastic, including photodegradation, tandem decomposition CO 2 reduction, selective oxidation, as well photoreforming plastic. This review concludes with a personal advances challenges conversion.
