ChemCatChem, EarlyView.Thermal enhancement of TiO2/Cu photocatalysis boosts H2 production from 3,847 µmol g−1 h−1 at 40°C to 10,421 µmol g−1 h−1 at 70 °C. Elevated temperatures improve charge separation and reaction kinetics while maintaining catalyst stability. The synergistic photothermal approach demonstrates Cu/TiO2 as an efficient, noble‐metal‐free system for ...

Simple Method for Transforming Liquid Silicone Oils into High‐Quality Solid Silicone Resins
Helvetica Chimica Acta, Accepted Article.A novel, cost‐effective and sustainable method for the synthesis of highly crosslinked methyl silicone resins by upcycling silicone oil, specifically linear polyorganylsiloxanes was developed. Using mild reaction conditions, a high yield of DT resins (up to 90%) along with silicone oligomers as a by‐product was achieved.
