Article Abstract
The oxygen evolution reaction (OER), a critical yet kinetically sluggish process in electrochemical water splitting, severely limits efficient hydrogen production. Herein, a simple one-step dynamic hydrogen bubble templated electrodeposition technique is used to prepare a self-supported 3D porous NiCuFeP catalyst with outstanding OER performance. In 1.0 M KOH solution, the optimized catalyst demonstrates a low overpotential of 236 mV at a current density of 10 mA cm, a small Tafel slope value of 48.2 mV dec, and significant stability over a period of 100 h at a current density of 50 mA cm. The reaction mechanism for the oxygen evolution reaction (OER) is elucidated further through density functional theory (DFT) calculations, providing atomic-level insights that explain the enhanced catalytic performance. In addition to developing a high-performance 3D porous OER electrocatalyst, this work suggests a general design approach for effective OER catalysts.

Nitrifying communities in activated sludge play a crucial role in biological nitrogen removal processes in municipal wastewater treatment plants. While extensive research has been conducted in temperate regions, limited information is available on nitrifiers in tropical regions. The present study investigated all currently known nitrifying communities in two full-scale municipal wastewater treatment plants in Malaysia operated under low-dissolved oxygen (DO) (0.

We herein construct the Ce-O-Ti interface bridge in the CeO/N-TiCT heterojunction through an ultrasonic-assisted hydrothermal route as an efficient Pt-free hydrogen evolution electrocatalyst. The synergistic contribution of the heterogeneous Ce-O-Ti bridge and oxygen vacancies boosts the water dissociation and thus drastically reduces energy barriers of the hydrogen evolution reaction (HER). The optimal CeO/N-TiCT material requires only a small overpotential (51.

Advancing impactful, economical, and durable Co-based bifunctional electrocatalysts for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) has been crucial in developing sustainable energy technologies. In this work, Co and CoN nanoparticles (NPs)-incorporated S, N-doped carbon catalysts (Co/CoN/SNC) were prepared via direct pyrolysis of the CoDATT complex, exhibiting high bifunctional electrocatalytic performance for ORR and OER. The complex precursor, CoDATT, was synthesized for the first time using diaminoterthiophene (DATT) and CoCl.
