Carbon Energy, EarlyView.Holey‐structured, edge‐carboxylated graphene with a controlled specific surface area was synthesized using an environmentally friendly, CO2‐activated, KOH‐free ball‐milling process. ABSTRACT Graphene, notable for its high specific surface area, is ideal for catalyst support but faces challenges under harsh thermal catalytic conditions.

Enhancing the Ferroelectricity of MAPbI3 via Hydroxyl Groups to Boost Photocatalytic Performance
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.The hydroxyl groups in (EOA)2PbBr4 enable a rearrangement of the polar MA+ ions in MAPbI3, which enhances the Ps‐electric field and promotes the separation of photogenerated carriers. Consequently, the (EOA)2PbBr4/MAPbI3 composite exhibits the enhanced CO production yield in photocatalytic CO2 reduction reactions.
