“…Although most BiVO 4 materials have different crystal phases and architectures and have been fabricated by adding the surfactant as a shape controlling agent [12][13][14][15], few feasible techniques are available for constructing practical and functional hierarchical nanomaterials. However, the pursuit of mild, versatile, and feasible techniques is a constant objective for materials scientists and chemists.…”

“…However, the pursuit of mild, versatile, and feasible techniques is a constant objective for materials scientists and chemists. Consequently, mimicking and replicating the morphologies of natural materials must be a potent shortcut used to control the shapes of photocatalytic materials [15]. Our team prepared FeVO 4 [16] and BiVO 4 via a sol-gel method using corn stem (CS) as a template.…”

“…For BiVO 4 , the value of n is 1. Thus, by plotting (αhν) 2 against hν, the band gap can be estimated [21,22].…”

“…As expected, the particles were orthorhombic, and the particle size was smaller than that prepared in the absence of EDTA. Zhu et al prepared BiVO 4 by the hydrothermal method in the presence of EDTA, and they obtained a mixed structure of monoclinic scheelite and tetragonal zircon with good crystallinity [21]. However, the effect of EDTA on the band gap and the photocatalytic efficiency has not been explored.…”

“…In recent years, monoclinic BiVO 4 (m-BiVO 4 ) has attracted considerable interest due to its narrow band gap compared with TiO 2 [2] and higher photocatalytic activity during the degradation of organic pollutant. Currently, various shapes of BiVO 4 have been prepared, such as sheets, tubes and spheres [3][4][5], but the high electronpairs recombination rate limits its application in the field of photocatalysis. Recently, the crystal facets exposed BiVO 4 was found that electrons and holes can be separated among the different crystal facets [6].…”
