摘要: When dealing with reactions of a liquid reactant and solid catalyst, macroreactors vigorous stirring equipment may be dangerous cause wastage energy. Reducing the diffusion distance promoting reactants to reach catalyst surface for efficient reaction remain key challenges. Here, inspired by capillary-driven water motion in plants, we propose implement self-driven multiplex (SMR) nanocatalyst-loaded microchannels. Unlike classical capillary rise, droplet SMR has variable pressure difference, leading tunable flow velocity controlling rate without any auxiliary equipment. The microchannels contributes an increase more than 2 orders magnitude compared that macroreactors. Specifically, this strategy reduces volume 170 times, usage about 12 energy consumption 50 times. This apparatus small less content promises provide precise manipulation chemical reactions.
