Many good thermoelectric materials contain rare or toxic elements, so developing low-cost and high-performance thermoelectric materials is warranted. Here, we report the temperature-dependent interplay of three separate electronic bands in hole-doped tin sulfide (SnS) crystals. This behavior leads to synergistic optimization between effective mass (m*) and carrier mobility (μ) and can be boosted through introducing selenium (Se). This enhanced the power factor from ~30 to ~53 microwatts per centimeter per square kelvin (μW cm^-1 K^-2 at 300 K), while lowering the thermal conductivity after Se alloying. As a result, we obtained a maximum figure of merit ZT (ZT _max) of ~1.6 at 873 K and an average ZT (ZT _ave) of ~1.25 at 300 to 873 K in SnS_0.91Se_0.09 crystals. Our strategy for band manipulation offers a different route for optimizing thermoelectric performance. The high-performance SnS crystals represent an important step toward low-cost, Earth-abundant, and environmentally friendly thermoelectrics.23:T4c0,Substituting the oxygen evolution reaction by the urea oxidation reaction (UOR) is thermodynamically more favorable for energy-saving hydrogen production. However, UOR suffers from sluggish reaction kinetics due to its complex six-electron transfer processes combined with conversion of complicated intermediates. Herein, LaNiO3–NiO heterojunctions successfully constructed to accelerate UOR. Systematic experimental investigation and theoretical calculation endorse that self-driven local charge redistribution takes place at the Janus LaNiO3/NiO interface, generating local nucleophilic and electrophilic regions. Such a unique structure is favorable for targeted adsorption of amino groups and electrophilic carbonyl groups, thus promoting the rupture of C–N bonds in urea. In addition, the build-in electric field triggered by LaNiO3–NiO heterojunction could effectively diminish the stepwise energy barrier, accelerating desorption of *CO2. As a result, the LaNiO3–NiO exhibits superior UOR performance, delivering a current density of 10 mA cm–2 at 1.34 V (vs RHE). This work supplies valuable insights for fundamental understanding and rational construction of efficient heterojunction UOR catalyst.
