“…This configuration was developed mainly as nanoparticles suspended in solution (Fig. 14 a) but also as a freestanding electrode system [ 131 ]. However, it is worth noting these large band gap semiconductors can only harvest UV and near UV photons that constitute about 5% of the whole solar spectrum.…”

HIGHLIGHTS• Different approaches for efficient carbon-free energy from water splitting are summarized.• Step-wise evolution of water splitting research is highlighted with current progress.• It describes the open challenges of charge transport properties and future research direction.ABSTRACT Sunlight is the most abundant renewable energy resource, providing the earth with enough power that is capable of taking care of all of humanity's desires-a hundred times over. However, as it is at times diffuse and intermittent, it raises issues concerning how best to reap this energy and store it for times when the Sun is not shining. With increasing population in the world and modern economic development, there will be an additional increase in energy demand. Devices that use daylight to separate water into individual chemical elements may well be the answer to this issue, as water splitting produces an ideal fuel. If such devices that generate fuel were to become widely adopted, they must be low in cost, both for supplying and operation. Therefore, it is essential to research for cheap technologies for water ripping. This review summarizes the progress made toward such development, the open challenges existing, and the approaches undertaken to generate carbon-free energy through water splitting.

“…A possibility is by using the transient absorption spectroscopic analysis to track the population and lifetime of the photogenerated charge carriers (electron-hole) within a photocathode upon the light excitation. For the case of TiO 2 light harvester activated by hybridizing with a CoP catalyst 6 , electron transfer events were well detailed by employing this technics. It was found that when a monolayer of CoP H 2 -evolving catalyst was used, photogenerated electron within the TiO 2 quickly transferred to the catalyst (in less than 10 µs), resulting an accumulation of valence band holes and a fast depletion of conduction band electrons.…”

Photoelectrochemical water splitting represents an attractive technological solution to harvest and then store the solar energy which is abundant but intermittent. It can be achieved by employing a photoelectrochemical cell, also called an artificial leaf. In order to construct viable photoeclectrochemical cells, efforts are being dedicated to engineer robust and efficient photocathodes for solar H 2 generation and photoanodes for solar water oxidation reaction. In this article, we discuss on the recent achievements and current perspectives in engineering of viable hybrid photocathodes. The state of the art on the design of a hybrid photocathode, its performance as well as the current understanding of its mechanistic operation will be first described. We then discuss on the technical strategies that are currently being developed to enhance the robustness and performance of a hybrid photocathode.

Silver nanoparticles (AgNPs) were synthesized in an aqueous solution via the reduction of AgNO3 employing citrate reducing agent. The resultant AgNPs were first assayed for the catalytic H2 evolution in an acidic electrolyte, namely pH 0.3 H2SO4 solution, showing negligible activity. The AgNPs were then conditioned in the same electrolyte solution while repeating the cyclic potential polarization between −0.25 V and 0.95 V (or 1.8 V) versus RHE. Effects of the electrochemical treatment to the morphology, crystalline, surface chemistry and H2 evolution catalytic activity of AgNPs were examined. It was found that the electrochemical treatment remarkably boosted the H2 evolution catalytic activity of AgNPs. The electrochemically activated AgNPs represents an attractive Pt‐free catalyst for the H2 evolution in acidic medium.
