However, the synthesis of mesoporous or macroporous liquids—such as those with uniform 20 nm mesopores—remains technically challenging due to the complex interplay of thermodynamic equilibrium and kinetic barriers.  In terms of catalytic directionality, microporous water was utilized to enhance the solubility of gases in electrolytes, thereby improving electrocatalytic conversion efficiency. However, its direct application in catalyst design and synthesis remains insufficient. The thermodynamic approach presented herein offers a promising strategy for synthesizing more efficient catalysts in liquid environments, potentially augmenting the density of catalytic sites and extending applications to photocatalysis, thermocatalysis, and related fields.
