Breakthrough in cobalt catalyst promotes production of photocatalytic hydrogen peroxide Researchers from the Dalian Institute of Chemical Physics have developed a new catalyst with uniformly dispersed individual cobalt atoms with a Co-N4 coordination structure. The team synthesized this material through thermal transformation using COPC as a precursor and phosphate functionalized reduced graphene oxide as a support. This catalyst, Co@rGO-P, was combined with perylenetetracarboxylic acid (PTA) nanosheets using an in-situ growth process to create efficient heterojunctions. The resulting Co?rGO-P/PTA photocatalyst achieved high activity for hydrogen peroxide (H2O2) production in pure water under visible light using a non-sacrificial approach. Hydrogen peroxide is…

Brazil’s Ministry of Mines and Energy is looking to woo Chinese companies for its first auction for battery energy storage, which is expected to improve grid stability and the integration of renewable energy sources. October 28, 2025 Livia Neves By ESS news Brazilian Minister of Mines and Energy Alexandre Silveira held bilateral meetings with Chinese energy companies such as Huawei Digital Power, BYD and CATL during a recent government mission through Asia, which also included business stops in Indonesia and Malaysia. The ministry wants to attract international investments for its first large-scale battery auction, scheduled for later this year. Battery…

MXene additive increases heat resistance and efficiency in perovskite solar cells As perovskite solar cells move closer to mass production, heat-induced degradation continues to hinder their long-term stability. Researchers from the University of Electronic Science and Technology of China, led by Professors Zhongquan Wan, Junsheng Luo and Chunyang Jia, have now demonstrated a multifunctional approach using Ti3C2Tx MXene nanosheets that improve both thermal conductivity and optoelectronic properties. The incorporation of Ti3C2Tx MXene into the perovskite layer significantly improves thermal transport, increases conductivity from 0.236 to 0.413 Wm-1-K-1 and reduces operating temperatures by approximately 3 C under illumination. At the same…

The researchers said their new discovery could open the way to the production of simpler solar panels made from a single material. October 30, 2025 Emiliano Bellini Researchers from the University of Cambridge in the United Kingdom claim to have discovered photovoltaic properties in a glowing organic semiconductor molecule known as poly(3-triphenylmethyl-thiophene (P3TTM). Unlike conventional organic semiconductors, which have paired electrons, organic radical semiconductors contain at least one unpaired electron per molecule, giving them an ‘open shell’ character. “In most organic materials, electrons are coupled and do not interact with their neighbors,” says lead author Biwen Li. “But in our…
