“…Noble metal nanoparticles (NPs) deposited onto MOFs can suppress electron-hole recombination rates due to the migrated electrons being trapped by the metal across a junction because of the Schottky barrier, whereas holes freely diffuse to the MOF surface. 90 There are some studies where the deposition of Pd, 91 Ag, 92,93 or Pt 20 NPs significantly improved the photocatalytic activity of MOFs in the degradation of pollutants. For instance, Miao et al 20 found that MIL-125(Ti)/Pt and MIL-125(Ti)/Ag photocatalysts exhibited a higher photocatalytic performance in the degradation of ketoprofen compared to the pristine MOF.…”

Heterogeneous photocatalysis has been considered one of the most attractive alternative routes to transforming naturally abundant, clean, and sustainable solar energy into chemical energy. Nowadays, the most popular heterogeneous photocatalyst, titanium dioxide, has already found applications for water splitting to produce hydrogen and oxygen, for the degradation of organic pollutants, for air purification, and for the creation of self‐cleaning coatings. However, TiO2 has a significant limitation: a large band gap (3.0–3.4 eV) that makes it impossible to use anything other than ultraviolet illumination to initiate photocatalytic processes. With a focus on efficient solar‐energy utilization, the development of new photocatalysts that are sensitive to visible light is an important direction in the theory and practice of heterogeneous photocatalysis. In this regard, the use of metal–organic frameworks (MOFs) is an attractive route; they have emerged as an interesting class of materials for applications in photoreactions due to their flexible tunability in composition, structure, and functional properties, along with their facilitated adsorption towards chemicals and their efficient light absorption. Moreover, they can be composed with other semiconductors to produce heterojunctions (e.g., type‐II, Z‐scheme, and S‐scheme), whose effectiveness in photogenerated charge separation has already been proven by many examples. The present critical review reports progress over the last 5 years in the preparation and activity of metal–organic framework‐based heterojunction photocatalysts for the degradation of organic pollutants. © 2022 Society of Chemical Industry (SCI).

“…Subsequently, SPR can expand the optical response range to the visible region. Therefore, the optical absorption edge of core@shell Ag/AgCl nanowire@MIL-100(Fe) 70 or Ag/NH 2 -MIL-125(Ti)/CdS red-shifts from B400 nm to B600 nm (Fig. 10(d-f 37 To strive towards usage of less metals due to their toxicity and high cost, MOFs have also been integrated with n-type organic supramolecular semiconductor perylene-3,4,9,10-tetracarboxylic diimide (PDI) to form a Z-scheme heterojunction as depicted in Fig.…”

“…20,21 The common methods to fabricate the Ag/AgCl electrode often include electrolytic and sintering. 17,22,23 The electroplating method has high efficiency, but AgCl generated by electroplating easily falls off and has a relatively short life. The sintering method is often used to prepare all-solid-state Ag/ AgCl electrodes.…”

The imposed interference by the signal electrodes limits the expansion of the measurement range in electromagnetic flow sensors (EFS). This is because the interference makes it difficult to increase the signal-to-noise ratio in the state of the microfluid. In this paper, an Ag/AgCl/porous graphite electrode sensor is successfully prepared by a chemical vapor deposition (CVD) method. This enables a high-reliability and wide measurement range surveillance system, which is also maintenance-free and cost-effective and has a long lifetime. AgCl is facilely synthesized by a mild method, and our analysis and experiments show that as-prepared AgCl nanoparticles demonstrate a high crystalline level and high quality. Further system testing and experiments are also conducted on EFS in cases where the Ag/AgCl/porous graphite electrode sensor is set as the core. It is seen that, within the flow range of 0.003−4 m 3 /h, the induced electromotive force is linearly related to the flow rate of the fluid. The measurement accuracy of the EFS using the transient measurement method is below 1%, and its sensitivity is not affected by the fluid temperature.
