A dual-functional Bi-doped Co₃O₄ nanosheet array towards high efficiency 5-hydroxymethylfurfural oxidation and hydrogen production

Abstract

Here we report that Bi-doped Co3O4 nanosheets array grown on Ni foam can selectively catalyze the HMF-to-FDCA oxidation at ambient conditions. The catalyst shows a Faradaic efficiency of 97.7%, a...

Cathode materials for halide-based aqueous redox flow batteries: recent progress and future perspectives

“…The three types of RFB systems are summarized in Table 3. 90–99 Presently, the bromine and iodine-positive electrodes appear to be more promising, owing to their high solubilities and kinetic reversibility as common electrode materials (CFs or GFs). 100–106…”

“…The three types RFB systems are summarized in Table 3. [90][91][92][93][94][95][96][97][98][99] Presently, the bromine and iodine-positive electrodes appear to be more promising, owing to their high solubilities and kinetic reversibility as common electrode materials (CFs or GFs). [100][101][102][103][104][105][106] So far, the ZBRFB has already been applied to LSESA.…”

Asymmetric Coordination Environment Engineering of Atomic Catalysts for CO2 Reduction

“…Furthermore, the attention on the CO 2 RR has extended to the catalytic environment, as the catalytic activity can be modulated by altering the structural parameters of the catalyst (solid)-electrolyte (liquid)-molecular reactant (gas) three-phase interface [ 144 , 145 , 146 ]. Some advances have been realized in these interfacial modulation studies, wherein it was discovered that controlling the proton supply or CO 2 supply can effectively inhibit the HER [ 147 , 148 ], electrodes with improved interfacial structures significantly improve selectivity and partial current density at relatively low overpotentials in H-type electrolytic cells [ 149 , 150 ], and membrane reactors and microfluidic reactors (flow cells) can achieve higher current densities [ 151 , 152 ]. Modification of the catalyst-electrolyte interface region also includes the addition of external molecules (or polymers), changes in electrolyte composition and concentration, the design of novel reactor and electrode structures, and a combination of these approaches, and these modification strategies can significantly affect the intrinsic and extrinsic catalytic activity of the catalyst.…”

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

“…The electrocatalytic N 2 reduction reaction (NRR) driven by renewable electricity is regarded as an attractive alternative to the Harber-Bosch route because it can hydrogenate nitrogen molecules with protons and electrons at ambient conditions. [8][9][10][11][12][13][14][15][16][17] Up to now, noble metal-based materials, [18][19][20] carbon-based materials, [21,22] and single-atom catalysts [23,24] have been developed for catalyzing the NRR to generate NH 3 ; however, the inert chemical property of N 2 molecule makes the reported NH 3 yield rates all far lower than that of industrial-level demand. Recent advances have confirmed that the electrochemical NO reduction reaction (NORR) could deliver a higher NH 3 yield rate (> 200 μg h À 1 mg cat.…”
