The electrocatalytic process of water splitting offers a promising approach to produce sustainable hydrogen. However, the slow kinetics oxygen evolution reaction (OER) presents notable challenge, especially in acidic environment proton exchange membrane (PEM) systems. Despite extensive progress made catalyst development for hydrogen production through electrolysis last century, significant advancements have been accomplished. quest OER catalysts that possess both high activity and stability,...
Binary metal nickel-iron alloys have been proven to great potential in oxygen evolution reaction (OER) electrocatalysis, but there are still certain challenges how construct more efficient alloy electrocatalysts and maximize their own advantages. In this work, a heterometallic cluster (L = C64 H66 Fe4 N8 Ni2 O19 ) of Schiff base (LH3 2-amino-1,3-propanediol salicylaldehyde) is designed as precursor explore its behavior the pyrolysis process under inert atmosphere. The combination TG-MS,...
The environmentally friendly and efficient recovery of valuable metals from spent lithium-ion batteries (LIBs) can mitigate environmental pollution enhance resource utilization efficiency. This study proposed a process for coating NCM cathode powder (LiNixCoyMnzO2) on graphite sheets the electrochemical leaching lithium.

Abstract 3Dtransition metal coordination clusters, as structurally diverse and designable metal‐organic hybrid systems, enable deliberate modulation of active sites bridging motifs within their structural kernels, making them ideal precursors for tailored nanostructures via pyrolysis. Through precise control over metal/organic ratios, the composition, spatial configuration, electronic structure derived nanomaterials can be effectively regulated, holding great promise establishing...
Transition metal oxides are widely pursued as potent electrocatalysts for the oxygen evolution reaction (OER). However, single-metal chromium catalysts remain underexplored due to their intrinsic activity limitations. Herein, we successfully synthesize mixed-valence, nitrogen-doped Cr2O3/CrO3/CrN@NC nanoelectrocatalysts via one-step targeted pyrolysis techniques from a binuclear Cr-based complex (Cr2(Salophen)2(CH3OH)2), which is strategically designed precursor. Comprehensive mechanisms...
Fenton-like reaction has been widely used for organics degradation. However, most works at low pH range (pH < 4) with uncontrollable selectivity of hydroxyl radicals from H2 O2 activation, and unsatisfied catalyst stability, which is compromised advanced oxidation performance water/wastewater treatments. In this work, to solve the drawbacks, novel copper catalysts were fabricated via hydrogen reduction/calcination Cu2+ -supported Al/MCM-41 precisely controllable valence state. Compared...
Exploiting stable and high-performance catalysts is a challenge in remediating organic pollutants (OPs) during advanced oxidation. Herein, this study reported MnFe2O4 decorated biochar (MnFe2O4/BC) as an adsorptive-catalyst for peroxymonosulfate (PMS) activation to degrade OPs. BC support not only increased the stability dispersibility but also decreased particle diameter of MnFe2O4. We demonstrated various OPs (50 mL, 20 mg·L−1) (including malachite green, bisphenol A, methylene blue,...
