14083 IUPAC Gold Book - regular surface site 10.1351/goldbook.14083 14083 current 1 Zero-dimension site (atom, ion, or interstitial position) at a regular surface. It can be a photocatalytic centre (site) in the ground (not active) state in some particular cases of heterogeneous photocatalysis as, e.g., in the case when pre-physisorbed entities trap photocarriers in the course of the photocatalysed reaction. heterogeneous photocatalysis https://goldbook.iupac.org//terms/view/14018 photocarriers https://goldbook.iupac.org//terms/view/14040 photocatalytic centre (site) https://goldbook.iupac.org//terms/view/14043 regular surface https://goldbook.iupac.org//terms/view/14082 PAC, 2011, 83, 931.
