In this study, we report the utilization of different water contents (0–40 vol.%) as cosolvent to ethaline,ChCl:EG (deep eutectic solvent) at the mole ratio of 1:2 to prepare binary oxide of tungsten oxide-molybdenum oxide nanocomposite in an ambient environment, followed by characterization using XRD,FTIR, SEM, TEM, TGA, XPS and UV–vis spectroscopy. The as-prepared composite composed of aggregatedparticles at low temperature of 60 C, in the crystallite sizes ranging from~48.40 to 71.97 nm, with watercosolvent acting as bad solvent. Further characterizations revealed that the atomic percentage ratios oftungsten and molybdenum components increase with decrease in carbon content as the water contentincreases, while the morphology changes from cubic to prismatic polyhedral-like structures at lowtemperature, in addition to retaining ~73% of its original weight above 700 C. The UV–vis analysisrevealed broad absorption at 239–374 nm with a threshold value of 527 nm and can attain maximumphotochromic response in less 60 s on exposure to UV–vis light irradiation.

Traditional herbal medicine has been playing an essential role in primary health care globally. The aim of this work is to present an overview of traditional herbal medicine research productivity over the past years. The data was accessed from the Scopus database (www. scopus. com), while VOSviewer.Var1.6.6, Bibliometrix, and R studio were used for further analysis of the obtained data. The results showed that researches on traditional herbal medicine increased annually after 1990, followed by a corresponding increase in global citations during the period, with a total of 22,071 authors contributing to all the publications. Yiling Wang of Shanghai Institute of Drug Control, Shanghai, China was the most productive author (TNP = 303), while Journal of “Evidence-based Complementary and Alternative Medicine”, and “Journal of Ethnopharmacology” were the top ranked journals, respectively. Also, China, Japan, and India were found to be the top Corresponding Author's Countries for researches on traditional herbal medicine, as Beijing University of Chinese Medicine, China Academy of Chinese Medical Sciences and China Medical University were top affiliations. Moreover, National Natural Science Foundation of China, National Key Research and Development Program of China, Ministry of Science and Technology of the People's Republic of China, and Ministry of Science and Technology, Taiwan were top funding agencies, with more than 100 documents. The bibliometric research study has revealed an annual increasing trend in traditional herbal medicine, while also revealing that the topmost ranked authors and funding agencies were from Asia especially China.

The present work is aimed at studying the synergistic catalysis of the bimetal ZIFs containing Co and Znmetal ions prepared by solvothermal method in the degradation of organic pollutants under ambientconditions. The bimetal mixed ZIFs were further characterized by some techniques such as XRD, SEM,TG-DTG, XPS, UV–vis, ESR, and N2-adsorption. Interestingly, the sample prepared with equal metal ions(1Zn:1Co) showed the highest catalytic performance for methylene blue (MB) degradation (94.10 %). Thismay be associated with the interaction between cobalt and zinc within the adjacent lattice, which makethe MB molecule to be easily adsorbed and degraded on empty electron orbit. Furthermore, the highestdegradation of MB was achieved with 98.83 % under the optimized conditions (catalyst weight of 50 mg,pH of 5, 3 h, 30 C). Besides, the various substrates such as methyl orange, indole, rofloxacin, methyl blue,and tetracycline were also investigated under the same conditions. Additionally, the DFT calculationresults suggested the more orbital distribution (LUMO, HOMO) of ZIF(1Zn:1Co) can result to more electronsbeing easily captured, and generate more radicals via electron transfer. Finally, the photocatalyticdegradation of MB is consistent with the first law of kinetics, and the activation energy is 26.797 KJ/molin the presence of ZIF(1Zn:1Co).
