Interfacial Engineering of Attractive Pickering Emulsion Gel-Templated Porous Materials for Enhanced Solar Vapor Generation

نویسندگان

چکیده

Solar vapor generation is emerging as one of the most important sustainable techniques for harvesting clean water using abundant and green solar energy. The rational design evaporators to realize high evaporation performances has become a great challenge. Here, porous evaporator with integrative optimization photothermal convention, transport thermal management developed attractive Pickering emulsions gels (APEG) templated followed by interfacial engineering on molecular scale. APEG-templated (APEG-TPEs) are intrinsically insulation materials conductivity = 0.039 W·m−1·K−1. After hydrolysis, t-butyl groups inner-surface transformed carboxylic acid groups, making hydrophilic facilitating through inter-connected pores. introduction polypyrrole layer endows light absorption ~97%, which could effectively convert irradiation heat. Due versatility APEG systems, composition, compressive modulus, porosity APEG-TPEs be well controlled efficiency 69% an rate 1.1 kg·m−2·h−1 achieved under simulated irradiation. interface-engineered promising in inspire future development evaporators.

High-Surface-Area, Emulsion-Templated Carbon Foams by Activation of polyHIPEs Derived from Pickering Emulsions

Carbon foams displaying hierarchical porosity and excellent surface areas of >1400 m²/g can be produced by the activation of macroporous poly(divinylbenzene). Poly(divinylbenzene) was synthesized from the polymerization of the continuous, but minority, phase of a simple high internal phase Pickering emulsion. By the addition of KOH, chemical activation of the materials is induced during carboni...
