A photocatalytic water splitting device for separate hydrogen and oxygen evolution.
A two-compartment Plexiglas cell has been set up and tested for separate hydrogen and oxygen production from photocatalytic water splitting on a thin TiO2 layer deposited by magnetron sputtering on a flat Ti electrode inserted between the two cell compartments.
متن کاملUltrathin HNbWO6 nanosheets: facile synthesis and enhanced hydrogen evolution performance from photocatalytic water splitting.
Ultrathin monolayer HNbWO6 nanosheets have been successfully prepared through a simple and ultrafast ion intercalation assisted exfoliation method. These obtained highly dispersed nanosheets present enhanced photocatalytic hydrogen evolution activity compared to the nanosheets prepared by the traditionally time-consuming process.
متن کاملAmorphous FeOOH oxygen evolution reaction catalyst for photoelectrochemical water splitting.
Reaching the goal of economical photoelectrochemical (PEC) water splitting will likely require the combination of efficient solar absorbers with high activity electrocatalysts for the hydrogen and oxygen evolution reactions (HER and OER). Toward this goal, we synthesized an amorphous FeOOH (a-FeOOH) phase that has not previously been studied as an OER catalyst. The a-FeOOH films show activity c...
متن کاملA novel photoreactor for separating hydrogen and oxygen in photocatalytic water splitting
H2 and O2 were produced in a twin reactor with two compartments divided by a Nafion membrane. Ce3+ and Ce4+ are adopted as redox mediator, which transferred the electron and holes between H2-evolving catalyst(Pt/SrTiO3:Rh) and O2 evolving catalyst (BiVO4). The optimal pH in the twin reactor was 1. Water splitting under Ce3+/Ce4+ equilibrium concentrations between two compartments gave the highe...
متن کاملExtended conjugated microporous polymers for photocatalytic hydrogen evolution from water.
Conjugated microporous polymers (CMPs) have been used as photocatalysts for hydrogen production from water in the presence of a sacrificial electron donor. The relative importance of the linker geometry, the co-monomer linker length, and the degree of planarisation were studied with respect to the photocatalytic hydrogen evolution rate.
