Sulfide, nitride, and phosphide semiconductors have long been identified as efficient materials to assist water splitting upon solar irradiation, but they unfortunately suffer from photocorrosion in aqueous solutions under illumination, as illustrated in the lower left part of the image. Promising and practical approaches to overcome this problem to achieve both stability and performance may rely on the engineering at the catalyst side. A thin yet dense layer of a stable material can be used to protect the unstable semiconductor from direct contact with the electrolyte, as shown in the upper left part of the image. Co-catalysts may also be deposited on the surface to accelerate the desired water oxidation/reduction reactions and in turn attenuate degradation, as illustrated in the central part of the image. Surface engineering can also be used, for instance, to form a built-in electric field layer to extract the unwanted charge carrier (photogenerated electron or hole, depending on the n- or p- nature of the surface material) away from the surface to avoid photocorrosion, as depicted in the lower right part of the image.

Photocatalytic hydrogen generation via water splitting has become a hot spot in the field of energy and materials. The goal of this technique is to construct cheap and efficient photocatalytic water splitting systems at an industrial scale, which first need us to search and develop efficient photocatalysts and suitable reductive/oxidative cocatalysts.
Among all the developed photocatalysts, graphitic carbon nitride (g-C3N4) as a metal-free photocatalyst has captured increasing attention largely due to its appealing properties of facile availability, low-cost and good stability, fulfilling the basic requirements for large scale industrial synthesis. However, its photocatalytic efficiency is rather low, mainly suffering from the limited efficiencies of the two primary processes in photocatalysis: charge carrier separation and surface catalytic redox reactions.
In a recent article published in Science Bulletin, Prof. Shaohua Shen's research group described an efficient photocatalytic hydrogen production system designed basing on promoting both of the charge carrier separation and surface catalytic redox reaction processes in g-C3N4.
In their study, g-C3N4 was loaded with ferrite (CoFe2O4 or NiFe2O4), which not only formed Type II band alignment with g-C3N4 to facilitate charge carriers separation, but also accelerated the surface electrocatalytic oxidative reaction kinetics. CoFe2O4 was further demonstrated to be a better modifier for g-C3N4 as compared to NiFe2O4, due to the more efficient charge carrier transfer as well as superior surface oxidative catalytic activity. When together loading CoFe2O4 and reductive hydrogen production electrocatalyst Pt onto g-C3N4, the obtained Pt/g-C3N4/CoFe2O4 photocatalyst achieved visible light (λ > 420 nm) hydrogen production rate 3.5 times as high as Pt/g-C3N4, with the apparent quantum yield achieving 3.35 % at 420 nm.
Surface activation of photocatalysts is central to H2 production from water via solar photocatalysis. In article number 1500153, M. Liu, L. Guo, and co-workers show, using shaped Cu2WS4 as model host photocatalyst, that a large percentage of the surface of the photocatalyst can be activated for H2 evolution by controllably depositing metal nanoparticles with tunable sizes onto targeted crystal facets.
