1. A titanated silica support consisting of:
a silica;
from 0.1 to 10 wt. % titanium;
from 0.5 to 12 wt. % water;
less than or equal to 3 wt. % carbon; and
an alkali metal and/or zinc;
wherein a molar ratio of the alkali metal to the titanium and/or the zinc to the titanium is from 0.05:1 to 3:1; and/or
wherein an amount of the alkali metal and/or the zinc is in a range from 0.04 to 2 mmol of the alkali metal or the zinc per gram of the silica.
