Herein, this work uses Ti 3 C 2 T x nanosheets to tune the work function (WF) of ZnMgO and to engineer the quantum dot (QD)/electron transport layer (ETL) interface. The B‐QLEDs with ZnMgO‐Ti 3 C 2 T x hybrid ETL exhibit a maximum EQE of 15.81% and a remarkable T 50 operation lifetime of 3284 h at 100 cd m −2 . In addition to that, ultraviolet photoemission spectroscopy and density functional theory calculations both confirm that the addition of Ti 3 C 2 T x to ZnMgO can effectively tune the ZnMgO's work function, further give rise to the reduction of QD/ETL energy barrier, which finally results in the alleviation of charge accumulation at the QD/ETL interface. The findings of interface engineering by Ti 3 C 2 T x not only provide a promising strategy for the application of 2D materials in optoelectronic devices, but also pave the way to construct high‐performance light‐emitting diodes.23:T533,Halide perovskites (HPs) are highly susceptible to heat, light, or moisture and are easily decomposed even in an ambient environment, which greatly hinders their practical applications. Herein, an in situ growth strategy is presented for implanting an inorganic lead-free HP, Cs₂AgBiBr₆, into SiO₂ sub-microcapsules to form a Cs₂AgBiBr₆@SiO₂ yolk-shell composite. The SiO₂ sub-microcapsule endows Cs₂AgBiBr₆ with good thermal and light stability, as well as excellent corrosion resistance against polar solvents. Furthermore, when employed as a lead-free perovskite photocatalyst, the composite exhibits a higher visible-light-driven CO₂-to-CO rate (271.76 μmol g^-1 h^-1) and much better stability than Cs₂AgBiBr₆ in water. The formation of a Cs₂AgBiBr₆/SiO₂ heterostructure using an in situ growth method alleviates water binding on the perovskites, supported by density functional theory calculations, which is the key to an improvement in the stability of the composite. The in situ growth strategy developed here sheds light on the design and development of HP-based materials for applications involving polar solvents.
