A high-efficiency photocatalyst with a strong built-in electric field was fabricated by anchoring π-conjugated molecules on the surface of crystalline nitride carbon via π–π stacking interactions with efficient photocatalytic CO ₂ reduction into CO and CH ₄ .

[P₄₄₄₄][Benoxa] ionic liquid was discovered to be very effective for the synthesis of benzothiazoles via cyclization of 2-aminothiophenols with CO₂ and hydrosilanes at ambient conditions, and a series of benzothiazoles were obtained in high yields.

Converting carbon dioxide into fuel and chemicals by utilizing solar energy represents a cutting-edge approach to carbon recovery and energy renewal. The transfer behavior of photogenerated electrons and built-in electric field of photocatalysts greatly affect the efficiency of the photoreduction reaction. Herein, the heterostructures composed of bismuth sodium titanate (BNT) ferroelectrics and silver nanoparticles (Ag NPs) are constructed to promote the photocatalytic CO2 performance. The large spontaneous polarization of BNT optimizes the transfer dynamics of photoinduced electrons and holes and causes energy band bending with strong intrinsic electric field. With the aid of Ag NPs, the BNT@xAg heterojunctions exhibit intensified light absorption due to the phenomenon of localized surface plasmon resonance (LSPR), which extends the visible light absorption spectrum and strengthens charge transfer. The modified catalysts demonstrate improved charge separation capacity and notably prolonged electron lifetime up to 40.95 ns. The synergistic effect of LSPR and intrinsic polarization significantly boosts the photocatalytic efficiency together with ultrahigh CO product selectivity, which is outstanding among the ferroelectric and other representative photocatalysts. This study elucidates the photocatalytic enhancement mechanism of plasmonic Ag decorated BNT and offers an alternative route for the design of efficient catalysts.

A well-designed CCN/Ni hybrid was constructed with a built-in electric field, accelerating photogenerated charge separation and migration as well as exhibiting improved CO₂ photoreduction performance.
