Iron and Nickel Substituted Perovskite Cobaltites for Sustainable Oxygen Evolving Anodes in Alkaline Environment

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Perovskite oxide catalysts with reduced Co content, substituted by Fe and Ni, are synthesized and studied for their activity in the oxygen evolution reaction in alkaline media. An increase in the intrinsic catalytic activity (obtained by the (RctCdl)−1 product) of the base material (Ba0.5Gd0.8La0.7Co2O6‐δ) is seen for an as high as 70 % substitution of

Low‐Temperature in Situ Upgrading of Ultra‐Deep Heavy Oil Using Ni–Ce/MOF–OTf Superacid Catalysts to Enhance Energy Utilization and Sustainability

EcoEnergy, EarlyView.
A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,

Interfacial and Ligand Dual Engineering Toward Energy‐Saving Hydrogen Production Coupled with Sulfion Degradation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Using a coordinated regulation strategy of interface and ligand, we developed a nickel cobalt sulfide/carboxylate ligand‐modified nickel cobalt hydroxide composite (NiCo‐S/NiCo‐OH‐CL) with abundant heterointerfaces. Owing to the porous network, sulfur‐repellent hydrophilic surface, and dual electronic structure regulation, the coupled electrolysis ...

Synergistic‐Induced Perovskite Phase Distribution and Lattice Stabilization for Efficient and Stable Sky‐Blue PeLEDs

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
We have developed a multifunctional buried‐interface engineering strategy using phenethylammonium thiocyanate to regulate quasi‐2D perovskite crystallization and stabilize the lattice. The synergistic effects of SCN− and PEA+ steric confinement promote phase redistribution toward n = 2, suppressing interfacial defects and enabling the production of ...
