Progress Report on pH-Influenced Photocatalysis for Active Motion

Living systems use catalysis to achieve chemical transformations comply with their needs in terms of energy and building blocks. The pH is a powerful means regulate such processes, which also influences synthetic systems. In fact, the sensitivity artificial photocatalysts, as bismuth vanadate, bears strong potential flexibly influencing both motion pattern speed catalytic microswimmers, but it has rarely been investigated date. this work, we first present comprehensive view behavior differently shaped vanadate discuss influences, shape, pH, conductivity solutions, find that swimmers switches between upright horizontal at point zero charge. We then apply an immobilizable hydroxypyrene derivative our substrates locally influence solution by excited-state proton transfer. strongly influenced functionalization third mode, called tumbling, introduced. Taking other effects, increased surface roughness modified substrates, into account, critically possible future developments.
