The results on the photocatalytic activity of 0 -2 wt.% Pt/g-C 3 N 4 in hydrogen evolution reaction under visible light (430 nm) are presented.Triethanolamine (TEOA), glycerol, glucose and cellulose were used as electron donor.During reaction, not only target product, hydrogen, but also by-products gas phase, namely CO 2 , controlled.In order to study chemical composition, microstructure optical properties, samples investigated by XPS, TEM diffuse reflection methods.The maximum rate obtained for 1 % from TEOA solution was 3.96 µmol•min -1 with a selectivity 100 %.The use glycerol resulted production syngas, varying platinum content allowed process vary (42.4 %).Glucose using led formation mixture H 90 or higher.In general, hydrogen-containing mixtures organic substrates can be further various applications.

Pt-TiO2 systems are the most widely used photocatalysts in production of green hydrogen from glycerol photoreforming. To incorporate metals on surface materials, photodeposition is method because it employs mild conditions. However, despite its use, there some parameters that have not been deeply studied, such as appropriate metal loading and itself, to obtain a better dispersion Pt. In this work, six catalysts were synthesized by classical employing UV radiation. The studied Pt wt.% range was 0.15–0.60 wt.%, being incorporated one step or subsequent ones. HRTEM analyses showed both methods allowed homogeneous distribution Pt, both, particle size around 2.3–3.6 nm, increasing with loading. photocatalytic activity materials tested photoreforming under radiation, 0.45 Pt-containing solid had highest production. This might suggest 0.40% for these conditions incorporating desired percentage efficient terms energy time savings.
