WebbIntroduction Proton-coupled electron transfer (PCET) reactions are pervasive in natural energy transfer processes, including photosynthesis, nitrogen fixation, and respiration. 1–4 Metal oxide semiconductor (e.g., ZnO, TiO 2, and SnO 2) nanoparticle-mediated photo-induced electron transfer has been directly proven to be a proton-coupled process. 5 … In chemistry, the number of protons in the nucleus of an atom is known as the atomic number, which determines the chemical element to which the atom belongs. For example, the atomic number of chlorine is 17; this means that each chlorine atom has 17 protons and that all atoms with 17 protons are chlorine atoms. The chemical properties of each atom are determined by the number o…
