Three-dimensional graphene (3DG) is promising for constructing monolithic photocatalysts for solar energy conversion. However, the structure-associated light-shielding effect and the intricate porous architecture of 3DG result in intrinsic limitations in light penetration and mass transfer over 3DG supported hybrids, which restricts their photocatalytic efficiency. Here, taking 3DG–organic hybrids as examples, we report a geometry regulation strategy to minimize such structural restrictions, which not only favors the interaction between light and the photoactive component, but also facilitates reactant adsorption over the 3DG–organic hybrids, thereby cooperatively boosting their photoactivity. Such an adaptive geometry regulation strategy is expected to guide the rational utilization of 3DG to construct high-performance hybrids for photoredox catalysis.

3D 石墨烯材料的自适应几何调控策略：迈向先进的混合光催化剂†

三维石墨烯（3DG）有望用于构建用于太阳能转换的整体式光催化剂。然而，与结构相关的遮光效应和 3DG 复杂的多孔结构导致 3DG 支持的混合材料在光穿透和传质方面存在内在限制，从而限制了其光催化效率。在这里，以3DG-有机杂化物为例，我们报告了一种几何调控策略，以最大限度地减少这种结构限制，这不仅有利于光和光活性组分之间的相互作用，而且还促进3DG-有机杂化物上的反应物吸附，从而协同促进他们的光活性。这种自适应几何调控策略有望指导合理利用 3DG 构建用于光氧化还原催化的高性能杂化材料。
