Soft-tissue fossils, such as those found in the Burgess Shale, are rare. In some cases their internal organs are replicated in phosphate. The phosphate mainly comes from the tissue itself, and may later be replaced by calcium carbonate. A low pH makes CaCO3 less likely to precipitate, clearing the way for phosphate to be laid down. This is facilitated by the absence of oxygen in the decaying tissue. Accordingly, (secondary) phosphate is generally only preserved in enclosed spa… WebIn summary, we first synthesized yolk–shell Ni 2 P/ZnP 2 hollow microspheres (NZP HMSs) through simple phosphatization of a bimetallic organic framework precursor, and further used them as a high-performance electrocatalyst for the OER.
