A photoelectrochemical (PEC) cell is able to realize effective solar-to-hydrogen energy conversion from water by using the semiconductor photoelectrode. Semiconducting colloidal quantum dots (QDs) with captivating features of size-tunable optoelectronic properties and broad light absorption are regarded as promising photosensitizers in solar-driven PEC systems. Up now, different types QDs have been developed achieve high-efficiency H2 generation, while majority state-of-the-art QDs-PEC systems still fabricated consisting heavy metals (e.g., Cd Pb), which extremely harmful human health natural environment. In this context, substantial efforts made mitigate usage highly toxic concurrently promote development alternative environment-friendly comparable features. This review presents recent advances devices based on several typical carbon QDs, I-III-VI III-V QDs). variety techniques shell thickness tuning, alloying/doping, ligands exchange, etc.) engineer these QD's production thoroughly discussed. Furthermore, critical challenges future perspectives advanced eco-friendly terms QDs' synthesis, photo-induced charge kinetics, operation stability/efficiency briefly proposed.

The presence of fractures increases the difficulty flow mechanisms analysis, and it remains unclear how affect multiphase displacement in layered rock matrix. Herein, a pore-scale imbibition model considering matrix-fracture system is established using phase-field method, where oil displaced by range fluids with various properties. Two typical modes are carefully analyzed, depending on locations fracture interfaces between different layers matrix: parallel to interface (mode I), penetrates through II), which dominated co-current countercurrent mechanisms, respectively. Interestingly, surface tension found be negatively correlated ultimate recovery rate for mode I plays an opposite effect that II. For I, conditions lower injection rate, higher viscosity ratio, grain diameter invading fluid from larger pore throat size (positive direction flow) can improve recovery. II, bifurcation angle has little positive flow, while significantly regulate phase distribution negative flow. Based scaling analysis relating pore-filling events equilibrium relationship capillary viscous forces, two theoretical models derived predict patterns, variation regime under parameters systematically concluded.
