Article Abstract
Improving the performance of CuO in electrocatalytic nitrite reduction to ammonia (NIRA) is the priority for designing efficient NIRA electrocatalysts. The electrocatalytic activity of CuO was enhanced by growing CoO nanospheres on it. By comparing CoO@CuO with the mechanically mixed CuO and CoO on a rotating ring-disk electrode, we discovered that the enhancement was attributed to a dual-site catalytic pathway.

MR-1, a Gram-negative bacterium with a significant role in the adsorption and reduction of uranium in wastewater and a quorum-sensing effect, can be used to remove uranium from wastewater. Exogenous signaling molecules (acyl-homoserine lactones, AHLs) can be added to induce the quorum sensing behavior for rapid biofilm formation, thereby improving the removal efficiency of this bacterium for uranium. Extracellular polymeric substances (EPS), as the significant components of biofilm, play a key role in biofilm formation.

Precise identification and detoxification of chromium pollution is important in effectively safeguarding ecological security and human health, while achieving the dual objectives of pollution prevention and resource regeneration. Herein, we synthesized dual-amine-functionalized carboxymethyl cellulose (CMC) material to develop a non-metal based integrated electrochemical process for centralized Cr(VI) detection, adsorption and reduction. Polyethyleneimine (PEI) and 5-aminosalicylic acid (5-ASA) were selected as amine-functionalizing additives.

Atomic hydrogen (H*)-mediated indirect electrochemical reduction has regarded as a highly effective strategy for halogenated organic pollutants (HOPs) removal in wastewater. The efficient generation and prompt utilization of H* are critical factors which directly determine the degradation performance. This study presented a new strategy for the electro-reduction of a typical HOP-2,4,6-trichlorophenol (2,4,6-TCP), achieved by modulating the electronic structure of a PdCo bimetal electrode (PdCo/CP).

In recent years, the overuse and improper disposal of antibiotics have led to their widespread presence in various environmental matrices and biological fluids. Exploring non-noble metal sulfides as electrocatalysts for reliable antibiotic detection holds substantial value but is limited by their inherent low electrochemical activity. Herein, CoS nanoparticles were first synthesized a hydrothermal method, and used for the assembly of ZnInS nanosheets.

Vehicle emissions of carbon dioxide significantly contribute to greenhouse gases. Recycling this CO₂ into valuable hydrocarbon products enhances vehicle mileage while reducing environmental impact, adding value to fuel consumption. This research aims to utilize the electrochemical method for conversion of CO to alcohols using nano-copper (Cu), silver (Ag), graphite (C), and their composites.
