Photocatalytic hydrogen production by biomimetic indium sulfide using Mimosa pudica leaves as template por Carrasco Jaim, Omar Ali, Ahumada Lazo, Rubén, Clark, Pip C.J., Gómez Solís, Christian, Fairclough, Simon M., Haigh, Sarah J., Leontiadou, Marina A., Handrup, Karsten, Torres Martínez, Leticia Myriam, Flavell, Wendy R.

“…Biomimetic sulfur-deficient indium sulfide (In2.77S4) was synthesized by a template-assisted hydrothermal method using leaves of Mimosa pudica as a template for the first time. The effect of this template in modifying the morphology of the semiconductor particles was determined by physicochemical characterization, revealing an increase in surface area, decrease in microsphere size and pore size and an increase in pore volume density in samples synthesized with the template. …”
