The contact angle of 0.1 m KHCO 3 on the three-phase heterojunction Cu/Cu 2 O-Sb 2 O 3 -15 (98°) was larger than that of the two-phase heterojunction Cu/Cu 2 O (77°), showing its hydrophobic nature in inhibiting the hydrogen precipitation side-reaction, which was complementary to the theoretical calculations.
Conclusion In summary, we proposed a heterojunction interlocked catalysis-conduction network in monolithic porous-pipe scaffold for endurable Li-S batteries. Therein the Co terminals of Co/Mo 2 C heterojunctions are interlocked to the catalytically grown CNTs.
Among all the tested samples, the three-phase heterojunction Cu/Cu 2 O-Sb 2 O 3 -15 electrode exhibited the best catalytic performance in terms of the Faraday efficiency of CO (FE CO) (Figure S11, Supporting Information) and CO partial current density (jCO) (Figure S12, Supporting Information).
Silicon heterojunction devices rely on the use of thin‐film silicon coatings on either side of the wafer to provide surface passivation and charge carrier‐selectivity. Beyond traditional indium tin oxide, multiple higher‐mobility indium‐based transparent conductive oxides have been employed successfully in HJT cells.
This heterojunction interlocked catalysis-conduction network shows unique advantages for the Li 2 S n conversion ( Fig. 7 g). (1) The three-dimensional scaffold constructed by the interlocked nanoclusters and CNTs is stable and can prevent the catalyst failure during long-term cycling.
We also found that this phase-heterojunction device exhibited better operating stability than the single-junction device counterparts, which may be due to the improved phase stability of the rear γ−CsPbI 3 absorber layer which acts as a capping layer 41, and dopant-free HTL could retard its perovskite to non-perovskite transformation.
