Aqueous ammonia is a potential absorbent for post-combustion carbon capture. Desorption of carbon dioxide (CO₂) and ammonia (NH₃) from ammonium bicarbonate (NH₄HCO₃) solution is one of key reactions of regeneration of the absorbent. Experimental studies on decomposition of NH₄HCO₃ solution with and without nano-TiO₂ at different temperatures were conducted. Additions of nano-TiO₂ into ammonium bicarbonate solutions decrease the apparent activation energy of overall decomposition reaction and accelerate the decomposition of ammonium bicarbonate solutions. Moreover, compared to hydrophilic nano-TiO₂, hydrophilic lipophilic nano-TiO₂ exerts more significant promoting effects on the decomposition reaction.

氨水是燃烧后碳捕获的潜在吸收剂。从碳酸氢铵（NH ₄ HCO ₃）溶液中解吸二氧化碳（CO ₂）和氨（NH ₃）是吸收剂再生的关键反应之一。进行了有和没有纳米TiO ₂的NH ₄ HCO ₃溶液在不同温度下分解的实验研究。向碳酸氢铵溶液中添加纳米TiO ₂降低了整体分解反应的表观活化能，并加速了碳酸氢铵溶液的分解。此外，与亲水性纳米TiO _2相比，亲脂性亲水性纳米TiO ₂对分解反应具有更显着的促进作用。
