Amino-modification, as an ingenious strategy, was proposed for boosting CO<sub>2</sub> electroreduction current density of Ni–N/C single-atom catalyst to industrial level.
Abstract Construction of single atom catalysts (SACs) with high activity toward electroreduction CO 2 still remains a great challenge. A very simple and truly cost‐effective synthetic strategy is proposed to prepare SACs via impregnation–pyrolysis method, through one‐step pyrolysis graphene oxide aerogel. Compared other traditional methods, this process fast free repeated acid etching, thus it has potential for facile operation large‐scale manufacturing. Both X‐ray absorption fine structure...
Abstract Engineering electronic structure to enhance the binding energies of reaction intermediates in order achieve a high partial current density can lead increased yield target products. Herein, amino‐functionalized carbon is used regulate tin‐based catalysts activity CO 2 electroreduction. The hollow nanotubes composed SnS (stannous sulfide) nanosheets are modified with layers, achieving highest formate Faraday efficiency 92.6% and remarkable 41.1 mA cm −2 (a total 52.1 ) at moderate...
Using renewable electric power to drive CO 2 electrochemical reduction high‐value‐added chemical fuels can not only solve the problem of excessive emission , but also achieve direct conversion intermittent electrical energy energy, which is great significance for controlling carbon balance and optimizing consumption structure. In recent years, various kinds electrocatalysts have been used in research reaction (CO RR) some progress has made key scientific issues such as improving selectivity...
The reaction current density for the CO2 electroreduction to formate of indium-based catalysts cannot meet needs industrial applications. Herein, nickel-doped indium oxide nanocrystals (∼7 nm) confined in carbon nanofibers (Ni-In2O3@C NFs) demonstrate a partial over 350 mA cm–2 at moderate overpotential 0.8 V, and particularly, Faradaic efficiency (FE) is above 90% wide potential region from −0.6 −1.0 V. More remarkably, long-term stability 55 h with an industrially relevant ∼200 can be...
We highlight the role of OH-treated weakly acidic ZSM-5 in ethanol-to-ethylene at low temperature. Ethylene forms via (i) primary dimer from ethanol on Brønsted sites, followed by diethyl ether cracking Lewis and (ii) secondary cleavage C–OH over sites.
Abstract Low‐range light absorption and rapid recombination of photo‐generated charge carriers have prevented the occurrence effective applicable photocatalysis for decades. Quantum dots (QDs) offer a solution due to their size‐controlled photon properties separation capabilities. Herein, well‐dispersed interstitial nitrogen‐doped TiO 2 QDs with stable oxygen vacancies (N‐TiO 2−x ‐V O ) are fabricated by using low‐temperature, annealing‐assisted hydrothermal method. Remarkably, electrostatic...

The extraction of higher-value products from lignin degradations under mild conditions is a challenge. Previous research reported efficient two-step oxidation and reduction strategies for degradation, which has great significance to degradation. In this paper, the mechanism about C-O bond cleavage with without Cα oxidations been studied systematically. Our calculation results show that degradation anionized kinetically thermodynamically feasible. addition, calculations predict compounds also...
Perovskite oxides have been widely used as catalyst due to their ordered structure, diverse chemical range and outstanding properties. However, there are few studies on the application of perovskite in CO2 electrocatalytic reduction reaction (CO2RR). In this paper, nanosized LaInO3 was successfully synthesized applied CO2RR. It displays excellent activity for formate production. The highest faradaic efficiency reaches 91.4 % partial current density is 106.8 mA cm−2 at a moderate...
Abstract An excellent catalyst can be effectively designed by adjusting its electronic structure. In this paper, an efficient hydrogen evolution reaction (HER) catalyst, carbon nanotubes with N doping and sublayer Co 4 encapsulating (N−CNTs@Co N) supported on Ni foam (NF), was prepared through a complementary structure principle. The as‐prepared N−CNTs@Co N@NF shows outstanding activity in 1.0 M KOH solution. DFT calculation indicated that wall of provided more competitive catalytic active...
