Improving Charge Separation in Cu2O/g-C3N4/CoS Photocathodes by a Z-Scheme Heterojunction to Achieve Enhanced Performance and Photostability

“…The visible light-driven photocatalytic activity of copper oxide photocathodes has been extensively studied for the hydrogen evolution from water, CO 2 reduction and degradation of organic pollutants (12)(13)(14)(15)(16)(17)(18). Cu 2 O is a p-type photocathode with a direct and suitable narrow bandgap of approximately 2.0 -2.2 eV (19)(20)(21)(22)(23), is nontoxic, has a large natural abundance, and is cheap to synthesize (24)(25)(26)(27)(28).…”

Synthesis and Characterization of Composites of Polyuthanes Obtained with Soybean Polyol/ TDI/ Minerals Fillers

“…Existem diferentes rotas para sintetizar polióis a partir de óleos vegetais tais como epoxidação, [14][15][16][17][18][19][20][21] hidroformilação, 10;22;23 ozonólise [24][25][26] e a hidroxilação 27,28 sendo que cada uma delas apresenta vantagens e desvantagens que são inerentes ao processo, sendo que, cada poliol sintetizado apresenta características distintas conferindo ao polímero uma gama de possibilidades de formulação cuja escolha dependerá de sua aplicação.…”
