1. An organic-inorganic hybrid material consisting essentially of a metal compound and a lignin fraction, wherein:
the metal compound is selected from metal hydroxide, metal oxide, metal halide, metal sulphate, metal nitrate, metal gluconate, metal acetate, metal carbonate, metal oxychloride, and combinations thereof, and the metal is selected from Mg, Ca, Ti, Fe, Mn, Co, Ni, Cu, Zn, Ag, Al, and mixtures thereof,
the lignin fraction comprises fragments having a weight average molecular weight of 4,400 Daltons to 6,000 Daltons and 24-33 phenylpropane units on weight average, a number average molecular weight of 1,200 to 1,300 Daltons and 6-7 phenylpropane units on number average, and wherein the metal compound is embedded in the lignin fraction in an amount up to 50 wt %, based on the weight of the organic-inorganic hybrid material, or
wherein:
the metal compound is selected from metal hydroxide, metal oxide, metal halide, metal sulphate, metal nitrate, metal gluconate, metal acetate, metal carbonate, metal oxychloride, and combinations thereof, and the metal is selected from Mg, Ca, Ti, Fe, Mn, Co, Ni, Cu, Zn, Ag, Al, and mixtures thereof,
the lignin fraction comprises fragments having a weight average molecular weight of 800 Daltons to 1,500 Daltons and 4-8 phenylpropane units on weight average, a number average molecular weight of 300 to 700 Daltons and 2-4 phenylpropane units on number average,
and wherein the metal is embedded in the lignin fraction in an amount up to 50 wt %, based on the weight of the organic-inorganic hybrid material.
