Cerium‐Modified TiO2 Nanomaterials Derived From Upcycled Coffee Ground Waste for Photocatalytic Oxidation and Hydrogen Production via Photoreforming

ChemistryOpen, Volume 15, Issue 10, October 2026.
Spent coffee grounds were valorized as a sustainable template for the solvent‐free synthesis of Ce‐loaded TiO2 photocatalysts, promoting enhanced Ce–Ti interactions and tailored morphology. The resulting materials were successfully applied in photocatalytic hydrogen production via ethanol photoreforming, gas‐phase 2‐propanol oxidation, and aqueous 5 ...

Synergistic Cobalt and Ytterbium Co‐Doping Enables Robust and Active IrRuOx for Acidic Oxygen Evolution Reaction

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Balancing low iridium dosage and robust anodic stability remains a critical hurdle for practical proton exchange membrane water electrolysis (PEMWE). Although IrRuOx offers a cost‐effective alternative, current systems still suffer from the dual dilemma of excessive noble‐metal reliance and inadequate long‐term durability. Herein, we developed

Modulating Oxygen Vacancies via Ag Induced Interfacial Electron Transfer in SnO2 for CO2 Electroreduction

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Regulating oxygen vacancies (Ov) in SnO2 to facilitate high‐efficiency carbon dioxide electroreduction reduction reaction (CO2RR) is still a significant challenge. Therefore, a strategy based on Ag‐induced interfacial electron transfer was proposed to modulate Ov in SnO2 for CO2 electroreduction. The prepared Ag/SnO2 with an optimal Ov content
