To settle the slow water oxidation kinetics and charge recombination of BiVO 4 photoanodes, boron-treated BiVO 4 combined with a NiFeOx electrocatalyst (NiFeOx/B/ BiVO 4 ) electrode is prepared. The resultant NiFeOx/B/BiVO 4 demonstrates a 5.22 mA/cm 2 current density at 1.23 V vs RHE under AM 1.5 G illumination without any sacrificial agent. Significantly, the applied bias photon-to-current efficiency of the NiFeOx/B/BiVO 4 photoanode reaches 1.96% at 0.7 V vs RHE, which is much higher than that of pristine BiVO 4 . Such excellent performance can be attributed to the existence of self-adsorbed [B(OH) 4 ] − ligands and NiFeOx electrocatalysts, enhancing the separation of photoelectron−hole pairs. This work provides a way to construct effective photocatalysts for solar water splitting.

Intensive competition of intellectual property, easy development of agrochemical resistance, and stricter regulations of environmental concerns make the successful rate for agrochemical discovery extremely lower using traditional agrochemical discovery methods. Therefore, there is an urgent need to find a novel approach to guide agrochemical discovery with high efficiency to quickly keep pace with the changing market. On the basis of these situations, here we summarize the intermediate derivatization method (IDM) between conventional methods in agrochemicals and novel ones in pharmaceuticals. This method is relatively efficient with short time in discovery phase, reduced cost, especially good innovated structure, and better performance. In this paper, we summarize and illustrate "what is the IDM" and "why to use" and "how to use" it to accelerate the discovery of new biologically active molecules, focusing on agrochemicals. Furthermore, we display several research projects in our novel agrochemical discovery programs with improved success rate under guidance of this strategy in recent years.
