Abstract
High purity carbon sorbent monoliths that are particularly effective for the adsorption and subsequent desorption of trace-contaminants, such as ammonia, are produced by 3D-printing polymer monoliths, carbonizing them, and subsequently activating them to produce an effective amount of at least one type of oxygen species on exposed carbon surfaces. The high purity carbon sorbent monoliths are vacuum-regenerable on a time scale of a few minutes.
