Carbon material is a hot topic in solar evaporation. Due to the widely distributed microorganisms in natural water, biofouling has limited the actual application of solar evaporation material. Although carbon material lacks of nutrition for microbe, it is still vulnerable to biofouling because of the efficient pollutant adsorption property. However, current anti-biofouling design focuses on microbial control, neglects its influence on evaporators light absorption, that is usually a trade-off with evaporation efficiency. Herein, a bioinspired aligned carbon-Ag
