Bamboo prepared carbon quantum dots (CQDs) for enhancing Bi3Ti4O12 nanosheets photocatalytic activity

Surface plasmon resonance effect of Ag nanoparticles for improving the photocatalytic performance of biochar quantum-dot/Bi4Ti3O12 nanosheets

“…Moreover, the XPS spectrum of the O 1s is as shown in Fig. 2d, the major peak at 529.4 eV was assigned to the oxygen in the BIT lattice, and the peak at 531.6 eV was related to the surface-adsorbed oxygen on the BIT [26]. Meanwhile, the peaks of C 1s assigned to the C-C sp 2 -hybridized carbon of CDs, C-O, and COO bands with the binding energy of a C 1s orbit were centered at 284.6, 285.4, and 288.4 eV, respectively ( Fig.…”

“…CDs and CD/BIT materials were prepared using the hydrothermal treatment of bamboo powder in our previous investigation [26]. Briefly, 3 g of bamboo powder was added to 30 mL of deionized water.…”

“…Through a typical synthesis of CD-modified Bi4Ti3O12 materials [26], a certain amount of CDs was dissolved in 5 mL of ethanol and using ultrasonic dispersion. Then, 0.1 g of Bi4Ti3O12 was added into the above solution and magnetically stirred at room temperature.…”

“…The dried composite was heated at 200 °C for 1 h in a N2 atmosphere. The optimum CD/BIT composites were prepared based on a previous study [26].…”

Growth Process and CQDs-modified Bi4Ti3O12 Square Plates with Enhanced Photocatalytic Performance

“…On the other hand, Bi 4 Ti 3 O 12 was frequently integrated with other semiconductors or decorated with noble metals to achieve excellent composite photocatalysts [40,41,42,43,44,45,46,47,48]. Very recently, Wang et al reported on bamboo prepared CQDs for enhancing Bi 4 Ti 3 O 12 photocatalytic activity [49]. Their work demonstrated that CQDs were a good modifier to enhance the photocatalytic activity of Bi 4 Ti 3 O 12 , although only 65% of ciprofloxacin was observed to be degraded at 90 min of photocatalysis.…”
