Article Abstract

NiCo O nanowire array on carbon cloth (NiCo O /CC) is proposed as a highly active electrocatalyst for ambient nitrate (NO ) reduction to ammonia (NH ). In 0.1 m NaOH solution with 0.1 m NaNO , such NiCo O /CC achieves a high Faradic efficiency of 99.0% and a large NH yield up to 973.2 µmol h  cm . The superior catalytic activity of NiCo O comes from its half-metal feature and optimized adsorption energy due to the existence of Ni in the crystal structure. A Zn-NO battery with NiCo O /CC cathode also shows a record-high battery performance.

Transition metal sulfides have emerged as promising alternatives to precious metal catalysts for sustainable electrocatalytic hydrogen production. However, achieving simultaneous optimization of active site exposure and vacancy-electron interplay remains a critical challenge. Herein, we develop a dual-regulation strategy integrating Fe-doping and high-temperature annealing to synthesize sulfur-deficient Fe-doped CoNiS@CC nanocatalysts (Fe-CoNiS@CC).

During thermal regeneration of styrene-saturated activated carbon (AC), styrene's C=C bonds are prone to polycondensation. It forms fixed carbon species that deposit as carbonaceous residues within AC pores, significantly decreasing the adsorption performance. To address this challenge for efficient AC regeneration and recycling, Ni and Co transition metal components were loaded onto AC and subsequently pyrolyzed to generate NiCoO active species.

Nickel-cobalt layered double hydroxides (NiCo-LDHs) are considered highly promising electrode materials for supercapacitors (SCs). Nevertheless, their limited conductivity and inherent stacking defects lead to inactive electronic states, thereby constraining their electrochemical performance. Here, a dual-conductive-engineered flexible electrode is fabricated through synergistic integration of in situ constructed 3D porous LDH with TiCT nanosheets deposition, establishing a semi-confined reaction microenvironment.

The electrochemical performance of electrode materials plays a pivotal role in determining the practical applicability of flexible supercapacitors, and optimization of material morphology has emerged as an effective strategy to augment these properties. This study presents the preparation of nickel cobalt cobaltite (NiCoO) nano-arrays exhibiting various morphologies, which serve as a support matrix. This is achieved through hydrothermal and annealing treatments applied to the surface of activated carbon cloth (CC).
