Key Highlights
•
Scientists have designed a new type of photocatalyst by breaking the molecular symmetry of a material called perylene diimide, which significantly improves its ability to split water using sunlight to produce hydrogen fuel. This breakthrough achieved an oxygen evolution rate of 19.19 mmol per gram per hour with a cocatalyst, and a quantum yield of 14.60% at 550 nm, pointing toward a promising strategy for creating more efficient solar-to-fuel conversion systems.

Researchers have found that ancient, low-permeability granite rocks in southern Finland can become viable geothermal reservoirs thanks to extensive fault systems and hydrothermal alteration that create natural fluid pathways. This work identifies five major fault-controlled geothermal targets in the Vehmaa Batholith, opening new exploration opportunities in stable, crystalline continental crust.

A new study demonstrates that carbon dioxide can be electrolyzed using a cobalt catalyst at high temperatures to produce longer-chain hydrocarbons (C4+), similar to the Fischer-Tropsch process, with the product distribution being strongly dependent on temperature. This finding is important because it offers a potential pathway to convert captured CO2 into valuable liquid fuels for transportation and industry.
