High concentration of siloxane groups represent the mesoporous or microporous [5, 6] in silica-pectin materials.
This result show similar data saying that the carbon chains produced from pectin (apples) strengthen the hydrostability of the materials.
However, the temperature of calcination may influence the carbon chains bonding in the silica-pectin materials.

All raw materials needed were weight according to the stoichiometric ratio.
All the raw materials were weighted.And then thoroughly grinded in agate mortar, placed in a corundum crucible, react in microwaveat mid-high fire for 30 min under reducing atmosphere.Redlight conversion agentswere obtained after cooling to room temperature.
The concentration of rare earth ions doped influences on luminescence property of materials remarkably (as shown in Fig.5).Fig.5 (1) showsthat the emission intensityof Ca0.6Sr0.4F2:Eu2+gradually increasedwith the increase ofEu2+when the doping concentration of Eu2+ is lower.

Among numerous photocatalytic materials, the metal oxide of perovskite-type offers themselves as one of the remarkable photocatalytic materials.
The perovskite materials possess diverse and interesting properties, such as the oxygen content in the materials, that lead to high catalytic activity and can be easily doped with metals in the preferred amount [2, 3].
Of these materials, Strontium titanate (STO) is well recognized as a promising photocatalytic material [1, 3].
