Water is the most common solvent in our daily lives. This solvent has advantages of green environmentalprotection and low cost. Water is conventionally considered to be an inert solvent, yet it is relatively polarand can form a large number of hydrogen bonds (HBs). But this property also inhibits the dissolution ofmany non-polar gases, causing many important electrocatalytic reactions performed in it to have lowefficiencies. In this work, we propose an innovative application of solar energy-generated active purewater (APW) with reduced HBs to enhance chemical reactions and physical procedures. Compared toconventional deionized water (DIW), the generated APW possessed a lower specific heat of ca. 0.96. The swelling degree of artificial skin in APW significantly increased by ca. 29%. Moreover, the densityof an ethanol/APW solution significantly increased by 0.21% due to more free water molecules beingavailable in APW to form stronger HBs with ethanol. Encouragingly, efficiencies of hydrogen evolutionreactions performed in an APW-based acidic solution and oxygen evolution reactions performed in anAPW-based basic solution significantly increased by 42% and 17%, respectively, compared to DIWbasedsolutions. The developed APW based on utilizing solar energy can create a more-effective greenprocess.
