Synthesis and characterization of binary selenides of transition metals to investigate its photocatalytic, antimicrobial and anticancer efficacy

Comparative Study of Selenides and Tellurides of Transition Metals (Nb and Ta) with Respect to its Catalytic, Antimicrobial, and Molecular Docking Performance

“…From spectra, it is shown that the prepared samples possess 16.0 wt% of Ta and 65.6 wt% of Te in C1 and 15 wt% of Nb and 66.3 wt% of Te in C2, these values are consistent with the relative atomic ratios of elements (~1:4) present in compounds TaTe 4 and NbTe 4 , respectively. Carbon and copper signals arise from the carbon-coated samples and Cu grids used for FESEM measurements [7,66]. No other peaks or elements associated to contaminations were observed in spectra which assure the purity of consequent products formed as a result of solid-state synthesis.…”

“…; C = S, Se, Te) are highly promising materials that are suitable for use in a number of industrial sectors including electronics, energy conversion and storage, photovoltaic, thermoelectric, and catalysis [1,2] owing to their desirable optical, electrical, and electrochemical properties [3]. Recently, selenides and tellurides doped with niobium and tantalum have received significant attention due to its potential use in applications such as in semiconductors, upper conversion of IR to visible light [4,5], gas sensors [6], laser diodes, medical diagnostics, photodetection devices, photocatalysis [7], superconductors, and topological insulators or semimetals [8]. Generally, transition metal chalcogenides exist as MC 2 , MC 3 , and MC 4 systems where M is known as a transition metal and C = S, Se, or Te [9].…”

“…In this regard, superconductivity in low-dimensional quasi (1D) tellurides (NbTe 4 ) with a large atomic number is under investigation [21,24]. To meet the increasing demand of nanostructured selenides and tellurides of TM in various fields, a number of approaches have been adopted to synthesize these materials including sol-gel [7,25,26], electrospinning [27], oriented-attachment process [28,29], chemical vapor deposition [30], organic solution-based high-temperature synthesis [31], template-directed method [32], and hydrothermal/solvothermal reaction [33].…”

“…Substantial environmental pollution caused by toxicity of organic dyes and pigments discharged as effluents from various industries remains a major source of health risk at a global level. It is not feasible to eliminate these non-biodegradable wastes through conventional water treatment methods [7,34] due to their complex aromatic structures, hydrophilicity, and stability against light, chemicals, and temperature [35,36]. Therefore, the development of effective, convenient, and economical degradation techniques has received paramount attention recently [37].…”

“…On the contrary, catalytic reduction process is a preferred option since it is relatively quick, inexpensive, and low-temperature treatment [35,37]. In this regard, several transition metal chalcogenides such as VSe 2 (photocatalyst and supercapacitor) [39], Yb-doped WTe 3 (ultra-short laser and amplifier) [40,41], TaSe 3 (superconductor), TaS and NbSe 3 (semiconductors) have been reported in the literature [7,27]. Here, it is pertinent to point out that much less attention has been paid to the study of catalytic reduction of methylene blue (MB) with NaBH 4 by utilizing compounds studied here.…”
