Co-immobilization of laccase and PEG modified COFs into Cu doped gel beads to achieve synergistic effect of photocatalysis and enzymatic catalysis for pollutants removal

Efficient and Recyclable Photobiocatalytic System via Cofactor Regeneration for Chiral Aryl Alcohol Synthesis

“…The swelled gel with a loose network after absorbing water led to unavoidable enzyme leakage during catalytic processes. For another, the generated charge carriers and ROS might attack the backbone of the gel, thus resulting in enzyme leakage and denaturation …”

“…Additionally, COFs are lightweight porous polymers composed entirely of light elements, which is not conducive to the separation and recycling of dispersed COF powder in practical applications . Inspired by enzyme entrapment widely employing alginate, which is a green matrix due to its biocompatibility and mild gelation process, coimmobilizing photocatalysts and enzymes into a stable alginate gelatin where photocatalysts and enzymes are trapped in the gel network while substrate and product molecules can freely transfer is a feasible approach from the aspects of enzyme protection and convenient recycling of both the enzyme and the photocatalyst. , …”

The metal-free photocatalyst COF TTA-T 2 was predesigned to possess a D−A structure and anticipated to be an excellent engine for artificial synthesis.…”

Efficient integration of covalent triazine frameworks (CTFs) for augmented photocatalytic efficacy: A review of synthesis, strategies, and applications

“…To enhance the absorption of visible light by derivatives of CTFs, along with the separation of e − /h + pairs and the overall η c , a spectrum of strategies has been devised to augment photocatalytic activity. These encompass the regulation of morphology and structure to expand specific surface area [ 39 , 81 , [104] , [105] , [106] , [107] , [108] ], the construction of defects [ 44 , 50 , [109] , [110] , [111] , [112] , [113] , [114] ], and the introduction of heteroatom doping [ [63] , [64] , [115] , [116] , [117] , [118] , [119] , [120] , [121] , [122] , [123] , [124] , [125] , [126] , [127] , [128] , [129] , [130] , [131] , [132] , [133] ] to tailor energy level configurations. Additionally, the fabrication of nanostructures and interfacial heterostructures has been employed to expedite carrier separation, among other approaches.…”
