The instability and low activity of WO3 is the hot-topic for photoelectrochemical (PEC) water splitting, which is decreased by a sluggish interfacial kinetics and incomplete water oxidation. Aiming at such issues, we designed a ternary WO3/RGO/Ni:FeOOH photoanode, which exhibits 2.05 times larger photocurrent (1.32 mA cm−2) than the WO3 NFs in 0.5 M Na2SO4 electrolyte solution, accompanied with 83 mV cathodic shift of onset potential. These results demonstrates PEC response can occurs only in Ni:FeOOH but not FeOOH. Therefore, Ni:FeOOH acting as bi-functional modifier, can not only increase light absorption but also promote charge transfer process by forming p-n heterojunction with the WO3 NFs. Besides, RGO forming a continuously conducting network can further improve charge separation process. Owing to their synergistic effects, the Faradaic efficiency and stability are both improved compared to its counterparts and the bare WO3 NFs. This work may inspire the PEC application in other co-catalyst decorated systems.

The determining method of the weights of multiple attributes decision making needs to be improved. Firstly, three entropy measures are deduced through a similarity measure of intuitionistic fuzzy sets. Most of the entropy measures are not able to fully describe the uncertainty of things. So the weight determining results which based on the entropy, becomes somewhat inaccurate. The method of improving the effective information is proposed to determine the attribute weights in order to improve the accuracy of weights determining. Ultimately the ideal multiple attributes decision making analysis results are determined by adjustment weights with the parameter.

The aim of this study was to solve the problems of mixed multiattribute group decision, which have the interval-valued, linguistic and interval-valued intuitionistic fuzzy number. As a solution to this problem, we propose a decision-making method that the decision maker weight was unknown, however, the attribute weight was known as well as the score function with transformation parameters. Firstly, conversion formula was used to make the mixed evaluation information unified transformed to the interval-valued intuitionistic fuzzy number. Furthermore, the decision maker and attribute weight were determined by the interval-valued intuitionistic fuzzy numbers distance and expectation values. Under the instruction of intuitionistic fuzzy weighted averaging operator, decision maker weight and attribute weight, we aggregated the individual decision making matrix and scheme different attribute successively. Additionally, we also made the dynamic scheduling analysis by the score function with transformation parameter. Finally, this method feasibility was testified by the example solving.
