Efficient and stable monolithic microreactor with Ag/AgCl photocatalysts coated on polydopamine modified melamine sponge for photocatalytic water purification

Utilizing Self‐Floating Cu3BiS3 Polydopamine Polyurethane Sponges for Enhanced Water Purification: Harnessing the free radical and non‐radical in persulfate system

“…Specifically, the degradation rates of TC were 78.75 %, 77.30 %, 76.80 %, and 74.68 % when the initial concentrations were 10, 15, 20, and 30 mg/L, respectively. The reason could be attributed to the limited availability of surface active sites and the decline in photon utilization as the number of TC molecules increases [31] …”

“…The reason could be attributed to the limited availability of surface active sites and the decline in photon utilization as the number of TC molecules increases. [31] To evaluate the effect of ambient water matrices on the PDS activation process, the TC degradation was conducted in deionized water, tap water and lake water. The adsorption capacity, degradation rate and total removal rate in the three types of water are shown in Figure 7b.…”

Multiphasic Continuous‐Flow Reactors for Handling Gaseous Reagents in Organic Synthesis: Enhancing Efficiency and Safety in Chemical Processes

“…[156] For example, Wang and co-workers have performed the photocatalytic degradation of methylene blue using a Ag/AgCl photocatalyst on a polydopamine-modified melamine sponge support to demonstrate its potential for water purification. [157] Methylene blue was degraded in 10 min under visible light irradiation at 250 L m À 2 h À 1 . Moreover, the authors demonstrated the recovery of the catalyst, making the monolithic reactor reusable and extending the lifetime of the system.…”

“…Although it is sometimes complicated to ensure sufficient light penetration in a monolith reactor, it is also possible to perform photocatalytic reactions in structured microreactors [156] . For example, Wang and co‐workers have performed the photocatalytic degradation of methylene blue using a Ag/AgCl photocatalyst on a polydopamine‐modified melamine sponge support to demonstrate its potential for water purification [157] . Methylene blue was degraded in 10 min under visible light irradiation at 250 L m −2 h −1 .…”

Synthesis, Structure, and Energetic Characteristics of Perovskite Photocatalyst SrTiO3: an Experimental and DFT Study

“…Effective utilization of the most widespread and promising energy sourcesolar radiation is one of the most critical problems, for the solution of which the search for new materials with improved optical properties is underway. Among them semiconductor photocatalysts are of the greatest interest due to their good study and wide range of possible applications: water splitting for hydrogen production [1][2][3], CO 2 reduction [4,5], water purification from pollutants [6][7][8][9][10][11], degradation of dyes [12,13] and others. However, due to the presence of a wide bandgap, the optical spectrum of semiconductor photocatalysts is limited to the ultraviolet zone [1], which is 3-5% of the total energy of solar radiation [14].…”
