Development of a simple aqueous solution based chemical method for synthesis of mesoporous gamma-alumina powders with disordered pore structure

Naik, B; Prasad, V S; Ghosh, N N (Springer, 2010)

A technically simple chemical method for the synthesis of mesoporous gamma-alumina has been reported. Mesoporous gamma-aluminas with different pore structure and surface area were synthesized by using aluminium nitrate as ...
A Facile Method for Preparation of TiO2 Nanoparticle Loaded Mesoporous γ-Al2O3: An Efficient but Cost-Effective Catalyst for Dye Degradation

Naik, B; Moitra, D; Dayananda, D; Hazra, S; Ghosh, B K; Prasad, S V; Ghosh, N N (American Scientific Publishers, 2016-08)

In this paper, we have reported the synthesis of a highly efficient TiO2 nanoparticle loaded mesoporous γ-Al2O3 catalyst for photocatalytic degradation of methyl orange under sunlight exposure. Pure anatase TiO2 nanoparticles ...
Preparation of CaO loaded mesoporous Al2O3: Efficient adsorbent for fluoride removal from water

Dayananda, D; Sarva, V R; Prasad, V S; Arunachalam, J; Ghosh, N N (Elsevier Science, 2014)

In this paper, we report a simple chemical method for the preparation of CaO loaded mesoporous Al2O3 based adsorbents, which can be used for fluoride removal from water. The synthesized adsorbents were characterized by ...
Preparation of TiO2, Ag-doped TiO2 nanoparticle and TiO2-SBA-15 nanocomposites using simple aqueous solution-based chemical method and study of their photocatalytical activity

Naik, B; Manoratne, C H; Chandrashekhar, A; Iyer, A; Prasad, V S; Ghosh, N N (Taylor & Francis, 2013)

Nanocrystalline TiO2, Ag-doped TiO2 and TiO2-SBA-15 nanocomposites have been synthesised using a simple aqueous solution-based chemical method. Nanocrystalline TiO2 was synthesised by calcining the precursor prepared by ...
Reduced graphene oxide−thioguanine composites for the selective detection of inorganic and organic mercury in aqueous media

Hiremath, S D; Maiti, K K; Ghosh, N N; Banerjee, M; Chatterjee, A (American Chemical Society, 2020-03-27)

Graphene oxide (GO) and its reduced form reduced GO (rGO) have received huge research attention because of their unique surface properties and diverse application potential. Here, a rGO-based turn-on fluorimetric sensing ...
A simple aqueous solution based chemical methodology for preparation of Mesoporous Alumina: Efficient adsorbent for defluoridation of water

Dayananda, D; Sarva, V R; Prasad, V S; Arunachalam, J; Ghosh, N N (Taylor & Francis Inc, 2015)

In this paper, we report a simple aqueous solution based chemical method for preparation of mesoporous gamma-Al2O3 which can be used for removal of fluoride ions from water. The synthesized Al2O3 and commercial Al2O3(Grade ...
A simple aqueous solution based chemical methodology for synthesis of Ag nanoparticles dispersed on mesoporous silicate matrix

Naik, B; Prasad, V S; Ghosh, N N (Elsevier, 2010)

A simple chemical method has been developed for preparation of Ag nanoparticles dispersed on mesoporous silicate matrix, SBA-15. Ag nanoparticles were uniformly dispersed on SBA-15 matrix by using the reduction reaction ...
