Ultrathin Polymers with Tunable Band Structures Boosted Multi-Functional Photocatalysis under Visible Light Illumination

“…In order to learn more about the effectiveness of charge separation and transport in the samples, electrochemical impedance spectroscopy was also performed. The MBAP sample has the smallest semicircular radius of the impedance spectrum (Figure d), indicating that it has the smallest resistance and the highest degree of charge separation during the photogenerated electron transfer process . To evaluate the charge separation of the polymer, we ultrasonically dispersed an equal mass of the sample in an equal volume of ethanol solution and then deposited the sample on a glass electrode sheet in a 0.1 M Na 2 SO 4 solution for photocurrent testing.…”

“…6 In particular, the choice of heterogeneous photocatalysis is one of the most researched methods for removing PhACs and is guided by its stability, sustainability, low cost, and ease of operation. 7,8 Regardless of its advantages, existing photocatalytic systems face several challenges, including material recovery, recombi- nation of electron−hole pairs, a narrow range of light absorption, reactor design, the toxicity of degradation byproducts, and high cost. 7,9,10 Recently, researchers have been addressing the majority of these limitations by developing suitable photocatalysts to overcome many of these drawbacks.…”

“…Numerous studies have been conducted worldwide to uncover alternate methods for the removal of PhACs from different water matrices, including advanced oxidation techniques that merit particular consideration . In particular, the choice of heterogeneous photocatalysis is one of the most researched methods for removing PhACs and is guided by its stability, sustainability, low cost, and ease of operation. , Regardless of its advantages, existing photocatalytic systems face several challenges, including material recovery, recombination of electron–hole pairs, a narrow range of light absorption, reactor design, the toxicity of degradation byproducts, and high cost. ,, Recently, researchers have been addressing the majority of these limitations by developing suitable photocatalysts to overcome many of these drawbacks. , In addition, different modification approaches, including metal and nonmetal doping and formation of heterojunction, have been harnessed due to their ability to achieve high stability, excellent separation and migration of photoexcited charge carriers, and high specific surface area (SSA). , Among heterojunctions, the Z-scheme configuration is most preferred for the possibility of efficient charge transfer of photogenerated electrons from one semiconductor to the other and reducing charge recombination in order to account for the overall improvement in photocatalysis . Another major challenge of photocatalysis is its application in real-world systems due to its small size.…”

Construction of surface electron island by a simple organic molecule adsorption strategy: tuning the energy band structure and boosting the photocatalytic performance

“…Photocatalytic water splitting for hydrogen production is a promising way to provide sustainable energy sources and reduce global warming effects. [1][2][3] Since Fujishima and Honda discovered that TiO 2 can produce hydrogen under illumination, many researchers have devoted themselves to improving the photocatalytic hydrogen evolution (PHE) performance of photocatalysts. 4 Many endeavors have concentrated on the doping of photocatalysts with noble metals, [5][6][7][8][9][10] transition metals [11][12][13][14][15][16][17] and non-metal materials [18][19][20][21][22] and coupling with semiconductors, 23 ternary photocatalysts, [24][25][26] and the well-dis-persed single atom structure.…”
