Green synthesis of CoWO4 powders using agar-agar from red seaweed (Rhodophyta): Structure, magnetic properties and battery-like behavior

Electronic properties and high-pressure behavior of wolframite-type CoWO4

“…41 Nonetheless, for CoWO 4 , the frequency of some of the modes differs significantly among previous experimental reports. 38,[44][45][46][47] These discrepancies are mostly observed in the low-frequency range, i.e. mostly external modes are affected.…”

Green fabrication of Co and Co3O4 nanoparticles and their biomedical applications: A review

“…These bioinspired cobalt ferrite NPs were characterized by various advanced techniques such as XRD, SEM, TEM, energy-dispersive X-ray spectroscopy (EDS), and XPS [ 91 ]. Similarly, cobalt tungstate (CoWO 4 ) NPs synthesized from red seaweeds ( Rhodophyta ) using agar-agar have also been reported [ 92 ].…”

Investigation of electronic structure, morphological features, optical, colorimetric, and supercapacitor electrode properties of CoWO4 crystals

“…According to the literature, the CoWO 4 crystals can be obtained via traditional routes performed at high temperatures (>900 °C) and long processing times (>4h) as conventional solid-state reaction, oxide-mixture, crystal growth flux and reduction/oxidation reactions [18][19][20][21][22][23][24][25][26][27]. In addition, other more elaborate synthesis methods have been employed to prepare the CoWO 4 (microcrystals, nanocrystals and films), including proteic sol-gel green [28], solid-state metahetic [29], polymeric precursor [30], facile refluxing-calcination [31,32], molten salt [33,34], conventional hydrothermal [35][36][37][38], microwave hydrothermal [39,40], precipi-tation or co-precipitation [41][42][43][44][45], sonochemical [46,47], alcoholthermal [48], spray pyrolysis [49], and pulsed laser deposition [50].…”
