Fabrication and photoelectrochemical properties of silicon nanowires/g-C3N4 core/shell arrays

Photo-electrochemical hydrogen production from neutral phosphate buffer and seawater using micro-structured p-Si photo-electrodes functionalized by solution-based methods

“…Over the past decades, they have thus gathered much attention towards photo-electrochemical (PEC) water splitting. [21][22][23][24][25][26] The band structure of n-type Si promotes the photoanodic oxygen evolution reaction (OER), 27,28 while p-type Si facilitates the photo-cathodic hydrogen evolution reaction (HER). 22 However, the difference between the potentials of the valence band edge of p-Si and that of the H + /H 2 redox couple is relatively small which limits the photo-voltage and leads to slow HER kinetics.…”

Optical properties of ZnO deposited by atomic layer deposition (ALD) on Si nanowires

“…The addition of zinc oxide (ZnO) as shells around SiNWs (as cores) can have substantial and beneficial impact on the stability, as well as on the mechanical, photoelectrochemical, and sensing properties when compared to bare ZnO nanowires fabricated with other techniques [30][31][32]. Si wafer is an attractive substrate because of its low cost, good thermal conductivity, high crystalline quality, and availability of large size substrates with different types of conductivity (doping).…”

Facile synthesis and photoelectrochemical properties of novel TiN/C3N4/CdS nanotube core/shell arrays

“…TiN/C3N4 nanotube arrays were synthesized by a LALD method (Fig. 1(a)) [50]. The TiN samples were immersed in the cyanamide aqueous solution with 25% mass concentration and keep it for 30 min.…”
