1D Ag@AgVO3 nanowire/graphene/protonated g-C3N4 nanosheet heterojunctions were fabricated and applied as an efficient photocatalyst for organic pollutant degradation.

Photocatalytic activity and NIR laser response of polyaniline conjugated graphene nanocomposite prepared by a novel acid-less method

“…A promising way of overcoming the existing barriers in the field is an efficient utilization of the solar energy [6,7]. In this context several new promising photocatalysts were suggested and tested recently for their catalytic activity [1–5]. Sunlight driven photocatalysis, in general, has a prominent ability in utilization of the solar energy conversion and environmental remediation.…”

Novel MoS 2 -modified AgVO 3 composites with remarkably enhanced photocatalytic activity under visible-light irradiation

“…From the high resolution Ag 3d spectrum shown in Fig. 3(b), two individual peaks centered at 367.8 and 373.8 eV can be observed, which corresponds to the binding energies of Ag 3d 5/2 and Ag 3d 3/2 , respectively [15]. As for the V 2 P spectrum shown in Fig.…”

Preparation of Zn2+–Ni2+–Fe3+–CO32−LDHs and study of photocatalytic activities for decomposition of Methyl Orange solution

“…It is well known that visible light absorption by the materials and the migration of the light-induced electrons and holes are the key factors controlling a photocatalytic reaction which is relevant to the electronic structure of the materials. [36][37][38][39][40] Generally, the photoabsorption of the photocatalysts depends on the mobility of the electron hole pair, which determines the probability of electrons and holes to reach the reaction sites on the surface of the photocatalyst. According to the experimental results, a potential mechanism is proposed and discussed as follows: firstly, when a Zn 2+ -Ni 2+ -Fe 3+ -CO 3 2− LDHs molecule adsorbs a photon with energy equal to or larger than its band gap, the excited electrons of LDH material were promoted from the valence band to the conduction band yielding holes (h + ) and photon-generated electrons (e − ) (see Equation (1)).…”
