나노-크기 플라워 부케 및/또는 삼각 퍼넬을 닮은 연장된 TiO결정자의 정렬된 침상 집합체, 및 카복시산 및 아미노 산으로부터 선택된 형태 조절제의 존재 하에 수성 용액 내에서 가용성 TiO전구체 화합물을 열적으로 가수분해함에 의한 그의 제조 공정. Ordered acicular aggregates of elongated TiO2 crystallites which resemble nano-sized flower bouquets and/or triangular funnels, and process for their preparation by thermally hydrolyzing a soluble TiO2 precursor compound in aqueous solution in the presence of a morphology controlling agent selected from carboxylic acids and amino acids.
