“…The thermal stability of the photocatalysts was tested by TGA analysis (Figure S1 in the Supporting Information). It was noteworthy that both CTF‐1 and Fe 10 /CTF‐1 were thermally stable up to a comparatively high temperature of 300 °C, attributing to the triazine moiety and high degree of polymerization in the conjugated network structures [33] . For the TG curve of CTF‐1, the initial weight loss at low temperature was the volatilization of surface moisture [34] .…”

Photocatalytic hydrogen energy production through water splitting paves a promising pathway for alleviating the increasingly severe energy crisis. Seeking affordable, highly active, and stable photocatalysts is crucial to access the technology in a sustainable manner. Herein, a trivalent iron‐doped covalent triazine‐based framework (CTF‐1) was elaborately designed in this study to finely tune the band structure and photocatalytic activity of CTF‐1 for H2 production. With optimal doping amount, Fe10/CTF‐1 exhibited a satisfying H2 production activity of 1460 μmol h−1 g−1, corresponding to 28‐fold enhancement compared with pure CTF‐1. The Fe3+ doping is responsible for a remarkedly broadened visible‐light adsorption range, improved reduction ability and inhibited electron–hole recombination of CTF‐1. Specifically, the doped Fe3+ could serve as photocatalytically active center and “electron relay” to accelerate charge separation and transformation. This study offers a feasible strategy to validly design and synthesize CTF‐based photocatalytic materials to efficiently utilize solar energy.

“…In this work, the photocatalytic activities of arsenomolybdates are investigated via the photodecomposition of organic dyes under UV light irradiation (Figure 3). The photocatalytic reactions were conducted using a common process [27]: arsenomolybdates and organic dyes solution were mixed and dispersed by ultrasonic. The suspension was stirred until reached the surface-adsorption equilibrium.…”

“…However, there is no stress and discuss on the progress of arsenomolybdates for degradation of organic dyes. Arsenomolybdates possess high-efficient proton delivery, fast multi-electron transfer, strong solid acidity and excellent reversible redox activity [27], which may result to prominent photocatalytic activities. In particular, the integration of metal-organic frameworks (MOFs) into arsenomolybdates for photocatalysis has attracted widespread attention over the past decade, since MOFs combine porous structural and ultrahigh internal surface areas.…”

Polyoxometalates (POMs) have fascinating structures and promising properties. The arsenomolybdates, as an important branch of POMs, are outstanding photocatalysts for organic dyes. In this work, we selected organic dyes to evaluate the photocatalytic activity of arsenomolybdates under UV light, containing compared with photocatalytic activity of different structural arsenomolybdates, stability, and the photocatalytic reaction mechanism of arsenomolybdates as photocatalyst. The arsenomolybdates may be used to as environmental photocatalysts for the degrading of organic dyes and solving the problem of environmental pollution.
