ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Bimetallic Cu and Fe oxide species supported on porous silica with interparticle mesoporosity act as efficient photo‐Fenton‐like catalysts under visible light. Photogenerated electrons drive the Cu2+/Cu1+ redox cycle. Part of Cu1+ is responsible for the regeneration of the Fe3+/Fe2+ cycle at neutral pH. Light irradiation additionally induces structural

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.LiNi0.5Mn1.5O4 (LNMO) precursors were produced at room temperature by Ambient Continuous Turbulent In‐line Mixing (ACTIM) at rates of up to 0.42 kg h−1. The final heat treatment step at 650, 700, or 750 °C, altered cation disorder and the electrochemical behavior of the LNMO cathodes, while the effect of adding MWCNTs to the electrodes, was also ...
