The author of the article were Yang, Xiya; Zhu, Peipei; Ma, Xiaoliang; Li, Wenjing; Tan, Zenglong; Sha, Jingquan. The article conveys some information:

A new polyoxometalate (POM) pillared metal-organic framework (POMOF), [Cu24(Trz)16(H2O)Cl4(HPMo12O40)] (Cu-POM, Trz = 1,2,3-triazole), was synthesized and characterized. Crystal anal. reveals that the Keggin POMs are inserted into copper-triazole layers with a graphite-like structure generating a POM-supported porous three-dimensional framework. Owing to the combination of the multi-electron redox property of POM units and the open porous framework, Cu-POM can be utilized as an anode material for lithium ion batteries (LIBs), and exhibits a reversible capacity of 525 mA h g-1 at a c.d. of 100 mA g-1 after 100 cycles. Moreover, to illustrate lithium storage, the impedance spectra of compound Cu-POM during the first and 100th charge process have also been studied. The study of Cu-POM in this work might guide the development of POM-based electrode materials for LIBs.

《Gas-phase UV absorption spectra and OH-oxidation kinetics of 1H-1,2,3-triazole and pyrazole》 was written by Samir, Brahim; Kalalian, Carmen; Roth, Estelle; Salghi, Rachid; Chakir, Abdelkhaleq. Safety of 1H-1,2,3-TriazoleThis research focused ontriazole pyrazole oxidation kinetics mechanism gas phase UV spectra. The article conveys some information:

In this work, we report the gas phase UV absorption spectra and the kinetics of the OH-oxidation of 1H-1,2,3-triazole and pyrazole. UV spectra were determined between 200 and 250 nm, at 350 ± 2 K and at pressures between 0.09 and 0.3 Torr. The reported maximal UV absorption cross sections are (cm2 per mol.): σ206 nm, 1H-1H-1,2,3-triazole = 2.04 x 10-18 and σ203 nm, pyrazole = 5.44 x 10-18. The very low absorption capacity of these compounds beyond 240 nm indicates that their atm. photodissociation is negligible. The OH-oxidation of these species was performed in an atm. simulation chamber coupled to an FTIR spectrometer and to a GC/MS over the temperature range 298-357 K and at atm. pressure. Experiments were conducted in relative mode using benzaldehyde, trans-2-hexenal and heptane as references The obtained rate constants at 298 K were (x10-11 cm3 per mol. per s): k(OH + 1H-1,2,3-triazole) = 2.16 ± 0.41; k(OH + pyrazole) = 2.94 ± 0.42. These results were compared to those available in the literature and discussed in terms of structure-reactivity and temperature dependency. Their tropospheric lifetimes with respect to reaction with OH radicals were then estimated In the experiment, the researchers used many compounds, for example, 1H-1,2,3-Triazole(cas: 288-36-8Safety of 1H-1,2,3-Triazole)

In 2019,Nature Catalysis included an article by Zhang, Lei; Liardet, Laurent; Luo, Jingshan; Ren, Dan; Gratzel, Michael; Hu, Xile. Quality Control of 1H-1,2,3-Triazole. The article was titled 《Photoelectrocatalytic arene C-H amination》. The information in the text is summarized as follows:

A strategy to use haematite, an abundant and robust photoanode, for non-directed arene C-H amination was described. Under illumination, the photogenerated holes in haematite oxidize electron-rich arenes to radical cations, which further reacted with azoles to give nitrogen heterocycles of medicinal interest. Unusual ortho selectivity was achieved, probably due to a hydrogen-bonding interaction between the substrates and the hexafluoroisopropanol co-solvent. The method exhibited broad scope and was successfully applied to the late-stage functionalization of several pharmaceutical mols.

The author of 《Nonpyrolyzed Fe-N Coordination-Based Iron Triazolate Framework: An Efficient and Stable Electrocatalyst for Oxygen Reduction Reaction》 were Huang, Zheng-Hong; Xie, Nan-Hong; Zhang, Min; Xu, Bo-Qing. And the article was published in ChemSusChem in 2019. Product Details of 288-36-8 The author mentioned the following in the article:

Pyrolyzed base-metal-based metal-organic frameworks (MOFs) with FeNx coordination are emerging as nonprecious metal catalysts for electrochem. oxygen reduction reaction (ORR). However, surprisingly, nonpyrolyzed MOFs involving Fe-N coordination have not been explored for the ORR. This study concerns the catalytic performance of a semiconducting nonpyrolyzed iron triazolate framework (FeTa2) for ORR in alk. electrolyte. The FeTa2 catalyst is studied as composites with different amounts of conductive Ketjenblack carbon (KB). The performance of these FeTa2-x KB (x denotes the KB/FeTa2 weight ratio) composites by onset and half-wave potentials of ORR appears to be superior to most previously documented nonpyrolyzed MOFs. Characterization by elemental anal., FTIR spectroscopy, XPS, and cyclic voltammetry suggest that N-FeIII-OH- sites at the surface of FeTa2 function as the catalytic active sites. This FeTa2 also shows very stable activity during ORR, as supported by accelerated durability test of the FeTa2-x KB sample (20 000 cycles, ca. 90 h). The framework structure of FeTa2 remains intact during the durability test, which would help to explain its excellent catalytic durability. This would be the first study demonstrating efficient and stable ORR catalysis by a nonpyrolyzed Fe-N coordination-based MOF material.
